Back

The prey population typically increases, but eventually, food shortages and disease can reduce the prey population.

Back

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

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the flow of energy and nutrients.
