What a food chain

This is my whats a food chain.

A food chain is an order of living organisms that shows us what eats what.

A food chain always starts with a producer for example plankton.

Then you have a consumer that eats the producer, for example a krill eats the plankton.

Next is a predator who eats the consumer, for example sardine fish eat the krill, the krill eats plankton.
