• There are two groups of animals which are important in agriculture. • The groups are domestic and wild animals. 1. Domestic animals • These are animals which are trained to live with people in their homes. • Some examples includes : Uses of domestic animals • Source of food, for example milk, eggs and meat. • For cultural purposes, for example paying lobola. • Some are used for transport and labour. • Domestic animals can also be a source of income. 2 . Wild animals • These are animals which are found in game reserves and in the forests • They are also called game animals. • Examples of wild animals are: Uses of wild animals • Some of the wild animals give us meat, hides and ivory. • Wild animals attract visitors from other countries, so the country gets money. Wednesday 06 September 2023 Exercise: Domestic animals 1. What is a domestic animal? [2] 2. What is a wild animal? [2] 3. Name any 4 domestic animals that you know. [4] 4. State any 2 uses of domestic animals. [2] 5. Name any 3 wild animals that you know. [3] 6. Give 2 uses of wild ani mals. [2] 7. Wild animals can also be called animals. [1] • Animals, like human beings need good food to help them to grow and reproduce. • The main sources of food for animals include stock feeds, pastures, veld grass, crop remains and cereal grains. • These foods contain the most needed essential nutrients. Nutrient Function carbohydrates Gives energy Fats Give energy and warmth Proteins Helps in growth and repair of body parts Minerals Help in the formation of bones and teeth Vitamins Help develop good sight, improve fertility and help animals fight diseases Water Transports food in the body, cools the body and remove waste from the body. • Livestock are domesticated animals that are kept for food, use or for sale. • Small livestock has many uses. • They are a good source of food. • They also give us manure to use in gardens. • We get clothes and medicine as well from small livestock • Examples of small livestock are rabbits, sheep, goats and all form of poultry Poultry • All animals that are kept by farmers which have wings and feathers and lay eggs are called poultry. • They are a good source of white meat, eggs and manure. • They are also a source of income when we well them and their products. • Poultry includes chicken, guinea fowl, ducks, turkey, pigeons and quail birds. Rabbits • Rabbits have 3 known uses which are: They are kept for meat Kept for pelts. (pelt is animal skin used to make blankets, hats and jackets) They are used at agricultural shows • Rabbits are cheap to buy, easy to keep and feed. • They take about 4 months to mature. • Rabbits are fed using green vegetables and rabbit pellets. Wednesday 20 September 2023 Small livestock 1. Give 3 examples of small livestock. [3] 2. State 3 things that are provided by small livestock. [3] 3. What are the 2 uses of rabbits? [2] 4. Pelts are used to make _________________ [1] 5. State any 4 examples poultry. [4] 6. Rabbits take ___________ months to mature. [1] 7. What is poultry? • Apiculture is the keeping of bees in order for them to produce honey for sale. • Apiculture is very important because: (i) Provides honey - a valuable nutritional food (ii) Provides bees wax - which has many uses in industry Uses of wax For making candles Polish furniture Make crayons Prevent tools from rusting (iii) Honey bees are excellent pollinating agents, thus increasing agricultural yields. BEE COLONY Inhabitants of the bee colony and their roles • A honey bee colony typically consists of three kinds of adult bees: workers, drones and the queen 1. Workers • Workers are the smallest and constitute the majority of bees occupying the colony. • They do not lay eggs. • Workers have specialized structures, such as brood food glands, scent glands, wax glands, and pollen baskets. • these allow them to perform all the labors of the hive. Roles of the worker bees they forage for nectar, pollen, water, and plant sap. They clean and polish the cells. feed the brood. care for the queen. remove debris. handle incoming nectar. build beeswax combs. guard the entrance. 2. Drones • Drones (male bees) are the largest bees in the colony. • They are generally present only during late spring and summer. • The drone’s head is much larger than that of either the queen or worker. • Drones have no stinger, pollen baskets, or wax glands. • Their main function is to mate with the queen. 3 . Queen • Each colony has only one queen. • The queen is the largest of the bees in a bee colony. • The Queen Bee plays a vital role in the hive because she is the only female with fully developed ovaries. • She produces both fertilized and unfertilized eggs. • Queens lay the greatest number of eggs in the spring and early summer. • The queen also produce chemical scents that help regulate the unity of the colony. 1. What is apiculture? [2] 2. Give 3 reasons why apiculture is important in Zimbabwe. [3] 3. Name the 3 inhabitants of the bee colony. [3] 4. Briefly explain the roles of each inhabitant named in number 3. • Apart from using hand tools, farmers also use some farm implements and machinery to carry out their field work. • Machines help farmers do their work more easily and quickly. • The most common implements used by farmers to grow, harvest and transport their produces are: mouldboard plough Cultivator Scotch cart Harrow Planter Maize sheller combine harvesters Boom sprayers Disc harrow Spike toothed harrow KNAPSACK SPRAYER • Farming is a business. • Communal farmers grow crops and keep animal mainly for their own use. • If there is any extra they sell to get money. • Commercial farmers grow crops and keep animals for sale. • Crops and animals produced are called farm produce. • There are places were farmers have to sell their produce. • Farmers can take their produce to local markets. • A market is a place where buying and selling occurs. • Some of the local markets includes: A shopping centre A school A nearest bus stop A local village A school Local Grain Marketing Board depot (GMB) Types of farm produce Beef Fruits Mutton Eggs Vegetables Pork Milk Chicken Cereals/grains beansOrchard / fruit trees Importance of fruit trees • Fruit trees are important for the following uses: They are a source of food, they produce fruits Some are used for making medicines Others provide shade and can also act as wind breakers. Those with beautiful flowers are very decorative. They contain vitamins which means they have nutritional value. Classification of fruit trees • Fruit trees are classified as indigenous and exotic. Indigenous fruit trees • are those that natural grow in a country. • They take longer to grow. • Examples of indigenous fruit trees are: English name Shona Name Snot apple Water berry Red ivory Fig Monkey orange Wild custard apple Mobola fruit Exotic fruit trees • These are trees that were brought from other countries. • They are commercially grown in orchards. • Common exotic fruit trees include: • Exotic fruit trees grow faster than indigenous. Ornamental horticulture • It deals with the growing of decorative plants. • Decorative plants are collectively called ornamental plants. • They include trees, shrubs, flowers and lawn grasses. Importance of ornamental plants They beautify the environment. Flowers often produce a pleasing fragrance. Flowers attract insects like bees that are responsible for pollination. Plants produce oxygen that we need for breathing. • Some are used for making medicines. • Lawn grasses prevent soil erosion. • Plants provide shelter for birds and insects. Classification of ornamental plants • There are four classes of ornamental plants. Trees Shrubs Flowers Lawn Trees: • Ornamental trees are very useful as decorative plants. • This is because most of these trees produce beautiful flowers and some are ever green. • Examples of decorative trees include flamboyant, jacaranda, pines, Cyprus. Shrubs: • A shrub is a woody plant with many branches but smaller than a tree. • Some of them are ornamentals because they produce beautiful flowers. • Others can be cut into decorative shapes. • The golden duranta is good example because it can be cut into nice shapes. • The bougainvillea is another example of a decorative plant because: It can act as a climbing plant. It produces decorative flowers. It can also be cut into any shape using a hedge shear. Flowers: • Flowers have the following functions: They are used for decorations at weddings, hotels and parties. They are used as an expression of love and appreciation such as valentine’s day and get well soon messages. They are useful in bee farming called apiculture as they are a source of nectar used for making honey. Flowers produce a pleasant fragrance used in the production of soaps and scents for perfumes, deodorant and lotions. Lawn: • A lawn is an area of grass that is kept cut short and is usually part of someone's garden or backyard, or part of a park. • Some lawn grasses grown in Zimbabwe are Durban, kikuyu, couch and buffalo lawn. • They prevent soil erosion. • They also provide a comfortable outdoor resting place. Forestry Importance of trees • Trees are important to us and animals. • The Forestry Commission is responsible for taking care of trees in Zimbabwe. • Trees are also important to the environment because: They are a source of fuel in the form of firewood. They are used for making most of the furniture we use. Most medicines come from both exotic and indigenous trees, for example pine trees and gum trees are used for making cough medicines. Trees provide browsing animals like the kudu and giraffe with food. Fruits from both exotic and indigenous fruit trees are a rich source of vitamins Trees give out oxygen which we need for breathing. Trees provide timber that can be used for roofing. • Trees are grouped according to where they come from. • The groups are indigenous and exotic. 1 . Indigenous trees : • These are local trees that have always been grown in their country. Shona name English name Mutohwe Snot apple Mususu Yellow wood Mubvamaropa Blood wood Muuyu Baobab Muonde Fig tree Musasa msasa Characteristics of indigenous trees take longer to mature Do not produce straight poles Grow on their own Hard wood 2 .Exotic trees : • These are trees that have been brought from another country to be grown in Zimbabwe. Characteristics of exotic trees They are brought in a country from another country. Grow very fast. Have soft woods Usually grow straight Usually grown in orchards and plantations Common exotic trees in Zimbabwe are: Gum trees Pine trees Wattle Cyprus Date palm Mango Apple pawpaw Causes of plant damage • plant damage is when cultivated crops are kept from normal growth that leads to reduced yields. • plant damage is caused by both living and non living things. • Some of the common causes of crop damage are: (a)Pests • These are living organisms that cause physical damage to crops. • Examples of pests are weevils, army worm, aphids, cutworms and locusts. (b) Diseases • Plant diseases are caused by living organisms called pathogens. • These pathogens infest the plant and take away nutrients. • Fruit rot and bacteria spot are some of the examples of plant diseases. (c) Weeds • these are plant which grow where they are not wanted. • For example if black jack grows in a groundnut field, it is a weed. • Weeds compete for nutrients with cultivated plants. (d) Very high temperatures • High temperatures may cause crops to wither. • High temperatures may also lead to lightning and fires. • This can burn up crops. ( e) Frost • Frost damages crops in winter. • Tomatoes, potatoes, and beans are easily damaged by frost. (f) Drought • drought is when there is no rainfall in a season where it supposed to be raining. • It is one of the most serious forms of crop damage. • Plants wither and die if there is no rainfall. ( g) Animals • Wild animals like baboons often eat maize crops before they mature. • Birds also are a problem to crops like sorghum. Signs of plant damage • There are various signs that show plant damage. • Some can be corrected but some lead to total loss. • Some signs of plant damage include: Lodged plants Flowers and small fruits blown to the ground Dull leaf color Wilted plants Stunted growthWHAT IS SCIENCE? - is a way in which answers related to NATURAL events are proposed. - a way in which people can learn and UNDERSTAND events in the NATURAL WORLD - based on OBSERVABLE EVENTS - a study of the NATURAL WORLD - a method of DISCOVERY and UNDERSTANDING by using a PROBLEM-SOLVING process called the?? - A systematic body of knowledge based on observation and experimentation. FOUR COMMON CHARACTERISTICS OF SCIENCE: 1. It focuses on the NATURAL WORLD. 2. Goes through experiment. 3. Relies on evidence. 4. Passes through the scientific community. WHAT IS TECHNOLOGY? Brian Arthur (2009) defined technology as: 1. a means to fulfill a human purpose 2. assemblage of practices and components 3. a collection of devices and engineering practices available to a culture. SOCIETY ST (Science Technology) would not exist without society. WHAT IS STS? Science and Technology and Society (STS) is the study of how society, politics and culture affect scientific research and technological innovation and how these, in turn affects society, politics and culture.
