2. Every living thing needs energy in order to survive. Every time animals do something (run, jump, move) they use energy to do so. Plants don’t move, so they use energy for growth.

3. Animals get energy from the food they eat, and all living things get energy from food. Plants use sunlight, water and carbon dioxide to get energy (in a process called (Photosynthesis).

4. Energy is necessary for living beings to grow. A food chain shows how each living thing gets food, and how nutrients and energy are passed from one organism to another. Food chains begin with plant- life(autotrophs/producers), and then energy is transferred to (heterotrophs/consumers).

5. Decomposers recycle and break-down the remaining matter after producers and consumers die. Fungi Bacteria Protists

6. A simple food chain could start with grass, which is eaten by rabbits. Then the rabbits are eaten by foxes. Arrows show energy transfer.

7. Are interconnected group of food chains. They show many feeding interactions among organisms in an ecosystem.
