- 3. RESPIRATION Plants use oxygenfrom the air to get energy from food during the process of respiration. They use carbon dioxide from the atmosphere to make their food during the process of photosynthesis.

- 5. Plants grow in soil.they get water and minerals from the soil to make food and to grow soil also provides plants with support.
- 6. Since animals dependon plants for food, they indirectly depend on soil for food. Soil provides shelter to animals such as ants, centipedes and earthworms. Rabbits, rats, moles and many other animals live in burrows in soil.
- 7. Water is essentialto all plants for carrying out their life processes. Plants absorb the minerals dissolved in water through their roots. They use water to prepare food during photosynthesis. Water also helps in the dispersal of seeds of plants growing in or near water.
- 8. Several life processesin the bodies of animals require water. For example, water is required to carry food to all parts of the body. Water is also essential for collecting waste from all over the body and removing it from the body in the form of urine.
- 9. Plants use energy trappedfrom sunlight to make food during photosynthesis. Sunlight provides warmth for seeds to germinate. Animals also need warmth from sunlight for survival. This Photo by Unknown Author is licensed under CC BY-SA

- 12. ANIMALS DEPEND ONPLANTS FOR FOOD. All animals depend directly or indirectly on plants for food. Herbivores such as cows, goats or giraffes eat plants and thus depend directly on plants for food. Carnivores such as tigers, lions or wolves eat other animals and so depend indirectly on plants for food.
- 13. ANIMALS DEPEND ON PLANTS FOR SHELTER Anumber of animals such as birds, squirrels, monkeys and insects find shelter on trees. Birds build nests on trees, while squirrels, monkeys and insects live on tree branches.
- 14. ANIMALS DEPEND ON PLANTSFOR OXYGEN Plants make food in the presence of sunlight, carbon dioxide and water. They give out oxygen during this process. Animals take in this oxygen during respiration.
- 15. PLANTS USE CARBONDIOXIDE PRODUCED BY ANIMALS During respiration, animals take in oxygen and give out carbon dioxide. This carbon dioxide is used by plants during photosynthesis.
- 16. PLANTS DEPEND ONANIMALS FOR REPRODUCTION Animals such as butterflies and honeybees help plants to reproduce by taking pollen from one flower or part of a flower to another. Many varieties of plants grow over a large area because birds and animals eat their fleshy fruits and scatter their seeds.

- 21. PRODUCERS Some organisms, knownas autotrophs, create their own food through photosynthesis. They get energy from the sun and nutrients from their surroundings (soil, water, etc.) that they in turn pass on to the organisms that eat them. They are PRIMARY CONSUMERS.

- 23. CONSUMERS The carnivores indirectlyutilise the food made by plants when they eat herbivores. They are SECONDARY CONSUMERS.

- 25. DECOMPOSERS HELP RELEASENUTRIENTS AND GAIN ENERGY FROM WASTE OR DEAD AUTOTROPHS AND HETEROTROPHS. Decomposers break down the dead body into simple substances which can again be used by plants.

Editor's Notes
- #26 In fact we would be buried more than knee deep in all sorts of dead matter that failed to decompose. Leaves are only one example.
- #31 We tend to think only of disease-causing bacteria, but these are in a minority. Most bacteria are either harmless or directly or indirectly beneficial. For example, cattle and sheep have a large population of bacteria in their stomachs where these beneficial bacteria help to digest the cellulose cell walls in grass.
