What is a food chain?

Food chain

A food chain shows how plants and animals get their energy.

Producers and consumers

A food chain always starts with a producer. This is an organism that makes its own food. Most food chains start with a green plant, because plants can make their food by photosynthesis.

A living thing that eats other plants and animals is called a consumer.

Predators and prey

A predator is an animal that eats other animals. The animals that predators eat are called prey. Predators are found at the top of a food chain.

This food chain shows a leaf is eaten by a worm, which is then eaten by a bird. The arrow means 'is eaten by'.
