Why is sunlight considered an abiotic factor in an ecosystem?

Sunlight is non-living and does not result from the activities of living organisms.

Sunlight is essential for the survival of all living organisms.

Sunlight contains living organisms within it.

Sunlight is produced by plants and is therefore living.

Why is soil considered an abiotic factor in an ecosystem?

Soil is a non-living component of an ecosystem that provides physical support and nutrients for plants.

Soil is directly involved in the process of photosynthesis in plants.

Soil is made up of living organisms like earthworms and bacteria.

Soil is dependent on the activities of animals for its formation.

Why is water considered a biotic factor in an ecosystem?

Water is a living organism that sustains life within an ecosystem.

Water is an inanimate substance that doesn't exhibit characteristics of living organisms.

Water is dependent on sunlight for its survival.

Water produces energy through photosynthesis in plants.

Abiotic and Biotic Factors in an Ecosystem

Create a review game for 9th grade biology students using the following topics Levels of Organization in an ecosystem- population, community, ecosystem, biome, biosphere Abiotic and Biotic Factors Differences between Food chains and food webs Trophic Levels Producers vs Consumers, Autotrophs vs. Heterotrophs Effects of Greenhouse gases and their effects on global systems. Biome examples Photosynthesis vs cellular respiration Types of Consumers Ecological Pyramids 10% rule Cycles of Matter/ Nutrient Cycles- Water Cycle, Carbon Cycle, Nitrogen Cycle, Phosphorus Cycle (note on the diagrams… the bigger the arrow, the larger amount of matter that moves through the cycle from that point to the next. Macromolecules- Carbohydrates, Lipids, Proteins, Nucleic Acids Nitrogen fixation Denitrification Eutrophication The usable form on nitrogen for plants is nitrate Population density and distribution-random, dispersed and clumped Birth rate and death rate Survivorship curves- Type I, II, and III Density dependent factors Density independent factors Exponential growth- J curve = unlimited resources, no limiting factors Logistical Growth-S curve= limiting factors, carrying capacity Symbiotic Relationships- Competition, predation, Herbivory, mutualism, parasitism, commensalism What is an invasive species? Why might countries limit certain species to coming into a new country or area? What is mycorrhizal? Succession- Primary vs Secondary Pioneer Species Climax community Biodiversity Climate change

Create a list of 20 questions based on the following objectives name some different types of ecosystems found in Antigua & Barbuda and other Caribbean countries, identify biotic and abiotic factors in specific ecosystems, compare and contrast ecosystems found in Caribbean countries. be sure to include multiple choice, short answer and open ended questions.

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.
