Energy flows in a food chain from producers to primary consumers, then to secondary consumers, and so on, with each level transferring energy to the next.

Front

What happens to a food chain if a key species is removed?

Back

Removing a key species can disrupt the balance of the food chain, leading to population increases or decreases in other species.

Front

What is a trophic level?

Back

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

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers; they are usually carnivores or omnivores.
