All living organisms need food to survive. Plants make their own food in their leaves. Plants are eaten by animals. These animals then become food for other animals, creating a food chain. In this example of a food chain, caterpillars and insects eat the plant leaves. These insects are in turn eaten by a bird which is then caught by a cat. All food chains start with the sun because plants need light to make food. Animals which eat only plants are herbivores. Animals which eat other animals are called carnivores.

Could be used for revision of terminology when learning about food chains and prior to creating some of their own. Alternatively it could be used during a plenary to help to reinforce and summarise the key facts. It could be used to promote discussions around the interdependence of plants and animals within a habitat and the possible effects of changes in the environment to the balance of the food chain.
