Back

The bottom layer is called the producer layer, which consists of organisms that produce energy through photosynthesis.

Front

What role do producers play in an energy pyramid?

Back

Producers convert sunlight into energy, forming the base of the energy pyramid and providing energy for all other levels.

Front

What are primary consumers?

Back

Primary consumers are organisms that eat producers; they are the second level in the energy pyramid.

Front

Decomposers break down dead organic matter, returning nutrients to the soil and completing the energy cycle.

Front

True or False: Decomposers are producers.

Back

False. Decomposers are not producers; they break down organic material instead of producing energy.

Front

What happens to the energy as it moves up the energy pyramid?

Back

As energy moves up the pyramid, it decreases at each level due to energy loss through metabolic processes.

Front

What would happen to the bird population if the green fish died out?

Back
