Habitat of Animals

Create a multiple choice test (10 questions with answers) from the following text: The Environment The environment is the combination of forces and conditions that surround and influence living and non-living things. Human beings’ environment includes such factors as temperature, food supply and other people that surround them. A plant’s environment may be made up of soil, sunlight, and animals that will eat the plant. A rock’s environment may be made up of seaweed, water and fish. Non-living environmental factors, such as temperature and sunlight, make up the abiotic (non-living) environment. Living organisms such as seaweed and food, make up the biotic environment. Both the abiotic and biotic environments interact to make up the total environment of living and non-living things. Ecology Ecology studies the relationships between living things and their environment. No living thing, plant or animal, lives alone. Every living thing depends in some way upon certain other living and non-living things to survive. The study of ecology increases our understanding of the world and all its creatures. This is crucial because humanity’s survival and well-being depend on relationships that exist on a world-wide basis: changes in distant parts of the world affect us and our environment. One concern of ecologists is the rate at which we are using up natural resources such as coal, gas, and oil. Along with scientists, they are searching for ways to use sunlight and atomic energy for fuel and power as alternative energy sources. Ecology also studies how many living organisms there are on Earth and how they are distributed. It also considers non-living physical factors of the environment, for example the presence of water, as these can influence where organisms decide to live. It is also important to know which organisms share the same environment, as they may need each other to survive. This kind of information helps ecologists to conserve our natural world, protecting the habitat of animals that are in danger of extinction, or trying to reduce pollution and global warming. Ecosystems Ecosystems are biological communities of all living things like plants, animals and organisms in a specific area that interact with each other and with the non-living forms present in their environment. They are the foundations of the biosphere and determine the health of the entire planet’s system. A biosphere is a global ecosystem, containing many different kinds of ecosystems.

Recap of Classification of animals according to their habitat

draw up a table with examples of animals and plants in a particular habitat, such as a garden, rice field, seashore, and mangrove swamp; 5. use flow charts to compare the different stages in the life cycle of animals, such as a butterfly, frog, chicken, and human; 6. use information from secondary sources to group animals according to the food they eat. Some are: a. plant eaters (herbivores), b. meat eaters (carnivores), and c. plant and meat-eaters (omnivores); and 7. draw a simple food chain using living things from the Philippines and label them as herbivores, carnivores, and omnivores.

The Philippine Flag Our country is officially identified through our flag. The Philippine flag has three colors: white, blue, and red. White signifies purity; blue means hope and peace; and red denotes bravery. The three stars symbolize the three big groups of islands of our country-the Luzon, Visayas, and Mindanao. The eight rays of the sun signify the eight provinces that first revolted against the Spaniards. These are Bulacan, Pampanga, Tarlac, Nueva Ecija, Laguna, Batangas, Manila, and Cavite. We respect our flag to show that we respect our country. We should not treat it like an ordinary cloth because it symbolizes our country. An old flag should be burned and not be used as a rag. Title: National Hero Body text: Dr. Jose Rizal was from a middle-class family from Calamba, Laguna. He is regarded as a genius who fought the Spaniards through his writings, especially the novels "Noli Me Tangere" and "El Filibusterismo." The two novels exposed the anomalies and wrongdoings of the Spanish government against the Filipino people. He wrote the poem "Mi Ultimo Adios" the eve before his execution in Bagumbayan (now known as Rizal Park). National Fruit A mango is sour when it is green, but very sweet when it is ripe. This heart-shaped fruit symbolizes the kindness of the Filipinos. It has a big tree that bears fruits abundantly during summer. National Animal A carabao is a model of hard work and industry. It is the best companion of farmers in the field. It is black and looks like a tamaraw. A carabao is a very strong animal in terms of work. It symbolizes the Filipinos as hardworking and patient. National Bird The Philippine eagle, also known as haribon, stands over 5 feet (1.6 m) tall. It has a large, sharp, and aggressive beak and has powerful talons. Philippine eagles are excellent hunters, and live in tropical rainforests. These eagles lay just one or two eggs each year. National Tree The narra is a hardy tree that grows big and is found mainly in the Bicol Region, Mindanao, and Cagayan Valley forests. Most of the desks and tables in schools are made of narra. It signifies the strong personality of Filipinos in facing trials in life. National Flower The sampaguita has white, star-shaped petals with a sweet fragrance. It is made into garlands, which are given to visitors and special persons on occasions. It signifies purity and among Filipino women. National Fish Bangus or milkfish is our national fish. It grows in ponds or freshwater and tastes delicious. Its white, shiny scales signify our beautiful country. National Dance Cariñosa is a dance of love using a handkerchief and a fan. It symbolizes the true love expressed by Filipinos. National House A nipa hut is a small but beautiful house made from bamboo and sawali or cogon leaves. Filipinos used this kind of house during the olden times. At present, there are still people using this as a dwelling place, but most of the time, they use it as a rest place or cottage. National Costume Barong Tagalog is the national costume for Filipino men. It is made from pineapple fiber or other native materials. Filipinos wear this on special occasions such as formal events or weddings. Baro at Saya is the national dress for Filipino women. Most of them are made from jusi or pineapple fiber and other native materials. This dress shows the gracefulness of Filipino women. National Leaf Our national leaf is a palm tree. It is wide and narrow like an open fan. Farmers use this to protect their crops from the harsh sunlight and rain. It grows like a tree with thorns in its body. National Language Our national language is Filipino, which is based in Tagalog. Through the efforts of former President Manuel L. Quezon (known as the "Father of the National Language"), Filipino was widely disseminated and is now used in all parts of the country. With this, Filipinos in different cultures and native tongues can still communicate with each other. National Food Lechon (litson) is an important dish served at many occasions, especially on fiestas. Lechon is a suckling pig, slowly roasted over live coals to make it crispy and tasty. National Footwear Bakya is the national footwear of the Philippines. It was most popular from the 1950s to the 1970s before the introduction of rubber slippers. There are several colors and designs of bakya that suit the taste of most Filipinos. Valuing Our National Symbols Symbols represent a country and its people. We have to respect and value these symbols because they tell something about our country and of who we are as Filipinos. Here are some ways of valuing our national symbols: When singing the national anthem, stand straight and place your right hand on your left chest. Remove your cap or close your umbrella. Ask the people walking to stop while the flag is being raised. Tell other children to stop chatting while singing the national anthem. Most importantly, sing the national anthem wholeheartedly. Retirement of a Flag: A worn-out flag should be disposed of respectfully. It should be burned in a dignified ceremony, not thrown away or used for other purposes. Help in saving and conserving our forests. They serve as habitat of our national bird and other animals. You may also help organizations that promote reforestation, clean and green programs, and tree planting activities. Do not pick flowers when visiting parks. Instead, help in keeping these places clean and beautiful. Avoid throwing thrash in their surroundings. Patronize products that are made here in our country and made by Filipinos. Tell your family and friends to buy products of the Philippines especially those of which are our national symbol. Aside from patronizing our own products, let us use and love our national language. It is good to learn foreign languages, but do not forget to use our own language correctly and proudly.

WHAT DOES THE WORLD GAIN WHEN WE PROTECT TIGERS? Tigers are one of the world’s most recognized animals. Throughout history they can be seen in cultural traditions across Asia, as well as in brand images and logos the world over. But while they might be omnipresent across our cultural landscape, their actual existence in the wild has been dramatically reduced to only a few pockets of their historical range. Wild tigers are now found in just 10 countries, their historical range shrunk by over 95%.er / WWF-US If tigers completely disappeared, we’d be losing so much more than an iconic species… Protecting water sources for millions of people Tiger habitats overlap nine of Asia’s most important watersheds which supply water to more than 800 million people. Protecting these tiger forests is the most cost-effective way to prevent droughts, reduce flooding, and limit the impacts of climate change. Protected Areas are proven to reduce deforestation and across Asia tigers are the driving force behind creating and effectively managing protected areas. For example, India recently declared its 51st Tiger Reserve, Srivilliputhur Megamalai, in southern India and this new protected area will safeguard more than 1,000km2 of key river habitat. Lose tigers, and lose entire forests Here in Cambodia, where I photographed the country’s last wild tiger in November 2007, tiger spirits were used by indigenous communities to help regulate the management of forests and wildlife. Harvesting of valuable plants was only permitted in certain times of the year and only after the tiger spirits had been appeased. Failure to adhere would result in wild tigers stalking you in the forest. However, with the extinction of the tiger the spirits have vanished, and the forests become an open free-for-all.aysia / Lau Ching Fong Protecting tigers also protects a multitude of other species Tiger-protected areas save much of Asia’s amazing wildlife. Take, for example, India’s Manas Tiger Reserve in Assam where tiger populations are increasing. In addition to tigers the grasslands and forests of Manas Tiger Reserve support the only viable global population of the world’s smallest, and rarest pig –pygmy hog – and, my personal favorite, the Bengal florican. This critically endangered gamebird, which I studied for my doctorate, finds a mate with an elaborate display involving males shooting themselves into the sky before plummeting down kicking their legs as if riding a bicycle. Without tigers, these and many more species would not be as well protected. A cultural and spiritual icon for millions There are plenty of examples of mythical animals, such as the unicorn, and extinct creatures, like the dodo and dinosaurs, which remain part of international consciousness. Tigers are a global phenomenon, but unless conservation is successful, they will only be known in zoos or in cultural media. A world without tigers would be economically and spiritually a much poorer place. Let us continue focusing our efforts towards doubling wild tigers and ensuring that this species does not become a vanished cultural icon.

Figure 18-11 represents the amount of energy stored as organic material in each trophic level in an ecosystem. The pyramid shape of the diagram indicates the low percentage of energy transfer from one level to the next. On average, 10 percent of the total energy consumed in one trophic level is incor- porated into the organisms in the next. Why is the percentage of energy transfer so low? One reason is that some of the organisms in a trophic level escape being eaten. They eventually die and become food for decomposers, but the energy contained in their bodies does not pass to a higher trophic level. Even when an organism is eaten, some of the molecules in its body will be in a form that the consumer cannot break down and use. For example, a cougar cannot extract energy from the antlers, hooves, and hair of a deer. Also, the energy used by prey for cellu- lar respiration cannot be used by predators to synthesize new bio- mass. Finally, no transformation or transfer of energy is 100 percent efficient. Every time energy is transformed, such as during the reactions of metabolism, some energy is lost as heat. Limitations of Trophic Levels The low rate of energy transfer between trophic levels explains why ecosystems rarely contain more than a few trophic levels. Because only about 10 percent of the energy available at one trophic level is transferred to the next trophic level, there is not enough energy in the top trophic level to support more levels. Organisms at the lowest trophic level are usually much more abundant than organisms at the highest level. In Africa, for exam- ple, you will see about 1,000 zebras, gazelles, and other herbivores for every lion or leopard you see, and there are far more grasses and shrubs than there are herbivores. Higher trophic levels con- tain less energy, so, they can support fewer individuals.A population is a group of organisms that belong to the same species and live in a particular place at the same time. All of the bass living in a pond during a certain period of time make up a pop- ulation because they are isolated in the pond and do not interact with bass living in other ponds. The boundaries of a population may be imposed by a feature of the environment, such as a lake shore, or they can be arbitrarily chosen to simplify a study of the population. The humans shown in Figure 19-1 are part of the pop- ulation of a city. The properties of populations differ from those of individuals. An individual may be born, it may reproduce, or it may die. A population study focuses on a population as a whole—how many individuals are born, how many die, and so on. Population Size A population’s size is the number of individuals that the population contains. Size is a fundamental and important population property but can be difficult to measure directly. If a population is small and composed of immobile organisms, such as plants, its size can be determined simply by counting individuals. Often, though, individ- uals are too abundant, too widespread, or too mobile to be counted easily, and scientists must estimate the number of individuals in the population. Suppose that a scientist wants to know how many oak trees live in a 10 km2 patch of forest. Instead of searching the entire patch of forest and counting all the oak trees, the scientist could count the trees in a smaller section of the forest, such as a 1 km2 area. The scientist could then use this value to estimate the population of the larger area. SECTION 1 OBJECTIVES ● Describe the main properties that scientists measure when they study populations. ● Compare the three general patterns of population dispersion. ● Identify the measurements used to describe changing populations. ● Compare the three general types of survivorship curves. VOCABULARY population population density dispersion birth rate death rate life expectancy age structure survivorship curve FIGURE 19-1 A population can be widely distributed, as Earth’s human population is, or confined to a small area, as species of fish in a lake are. Copyright © by Holt, Rinehart and Winston. All rights reserved. 382 CHAPTER 19 If the small patch contains 25 oaks, an area 10 times larger would likely contain 10 times as many oak trees. A similar kind of sampling technique might be used to estimate the size of the pop- ulation shown in Figure 19-2. To use this kind of estimate, the sci- entist must assume that the distribution of individuals in the entire population is the same as that in the sampled group. Estimates of population size are based on many such assumptions, so all esti- mates have the potential for error. Population Density Population density measures how crowded a population is. This measurement is always expressed as the number of individuals per unit of area or volume. For example, the population density of humans in the United States is about 30 people per square kilome- ter. Table 19-1 shows the population sizes and densities of humans in several countries in 2003. These estimates are calculated for the total land area. Some areas of a country may be sparsely popu- lated, while other areas are very densely populated. Dispersion A third population property is dispersion (di-SPUHR-zhuhn). Dispersion is the spatial distribution of individuals within the popu- lation. In a clumped distribution, individuals are clustered together. In a uniform distribution, individuals are separated by a fairly con- sistent distance. In a random distribution, each individual’s location is independent of the locations of other individuals in the popula- tion. Figure 19-3 illustrates the three possible patterns of dispersion. Clumped distributions often occur when resources such as food or living space are clumped. Clumped distributions may also occur because of a species’ social behavior, such as when animals gather into herds or flocks. Uniform distributions may result from social behavior in which individuals within the same habitat stay as far away from each other as possible. For example, a bird may locate its nest so as to maximize the distance from the nests of other birds. These migrating wildebeests in East Africa are too numerous and mobile to be counted. Scientists must use sampling methods at several locations to monitor changes in the population size of the animals.

Each gannet chooses a small nesting area on the coast and defends it from other gannets. In this way, each gannet tries to maximize its distance from all of its neighbors, which causes a uniform distribution of individuals. Few populations are truly randomly dispersed. Rather, they show degrees of clumping or uniformity. The dispersion pattern of a population sometimes depends on the scale at which the popu- lation is observed. The gannets shown in Figure 19-3b are uni- formly distributed on a scale of a few meters. However, if the entire island on which the gannets live is observed, the distribution appears clumped because the birds live only near the shore. POPULATION DYNAMICS All populations are dynamic—they change in size and composition over time. To understand these changes, scientists must know more than the population’s size, density, and dispersion. One important measure is the birth rate, the number of births occur- ring in a period of time. In the United States, for example, there are about 4 million births per year. A second important measure is the death rate, or mortality rate, which is the number of deaths in a
