All living things need food to give them the energy to grow and move.

What is a food chain?

A food chain shows how each living thing gets its food. It shows who is eating who. The arrow means "is eaten by" .
Grass ----> Grasshopper ----> Toad ----> Snake ----> Eagle

Grass is eaten by Grasshopper is eaten by Toad is eaten by Snake is eaten by Eagle
Answering questions about food chains
You may be asked to link a plant, which is a producer, to an animal, which feeds on it and is known as a consumer and then to another animal, also a consumer, which feeds on the first animal.
Always use an arrow which points from the producer to the consumer
eg: nettle -----> caterpillar -----> bird
