What happens to the number of plants if primary consumers are removed from an ecosystem?

Back

If primary consumers are removed, the number of plants would likely increase due to reduced grazing.

Front

What is the energy pyramid?

Back

The energy pyramid is a graphical representation of the energy flow in an ecosystem, showing the amount of energy available at each trophic level.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.

Front

What is a carnivore?

Back

A carnivore is an animal that primarily eats other animals. Examples include lions, wolves, and hawks.
