Back

The transfer of energy from one trophic level to another, starting from producers to various levels of consumers.

Front

What is a food chain?

Back

A linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What is a trophic level?

Back

Each step in a food chain or food web, representing a different level of energy transfer.
