An introduction to food chains
All living organisms need food to survive. Plants make their own food in their leaves and are eaten by animals. These animals then become food for other animals, making 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 - plants need light to make food. Animals which eat only plants are herbivores. Animals which eat other animals are called carnivores.
