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 to highlight the fact that plants and animals both need food to survive. This clip would introduce the pupils to the terms carnivore, herbivore and omnivore before starting work identifying and naming some common examples. It could also be used to focus the pupils’ attention on specific groups of living things before engaging in classifying and sorting tasks.
