Energy Pyramids, Food Chains & Webs

Front

What is a food chain?

Back

A food chain displays the sequence of organisms that consume one another.

Front

Why are producers found at the base of the energy pyramid?

Back

Producers are at the base because they create all of the energy and have the most energy of all trophic levels.

Front

Which level has the most energy available in an energy pyramid?

Back

The producer level has the most energy available.

Front

How do producers obtain energy?

Back

Producers obtain energy by conducting photosynthesis.

Front

What is a food web?

Back

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

Front

What role do primary consumers play in a food chain?

Back

Primary consumers are organisms that eat producers (plants) for energy.

Front

What is the difference between a food chain and a food web?

Back

A food chain shows a single pathway of energy flow, while a food web shows multiple interconnected pathways.

Front

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

Back

Energy decreases as it moves up the energy pyramid due to energy loss at each trophic level.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organisms and recycle nutrients back into the ecosystem.

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 energy.
