A food chain is a linear sequence of organisms in an ecosystem, where each organism consumes the one below it and is consumed by the one above it. It represents the flow of energy and nutrients through different organisms in an ecosystem. For example, a simple food chain in a forest ecosystem could be: grass is eaten by a rabbit, which is then eaten by a fox.

A food chain is a linear sequence of organisms through which nutrients and energy pass, starting with a producer organism and ending with a top predator. Each organism in the food chain feeds on the one below it, and is in turn eaten by the one above it.
For example, in a simple food chain, grass grows (producer), grasshoppers eat the grass (primary consumer), birds eat the grasshoppers (secondary consumer), and hawks eat the birds (tertiary consumer).
Food chains are important because they show how energy and nutrients flow through an ecosystem. They also help to regulate population sizes, as predators can limit the number of prey available.
