Food Webs, Chains, and Energy pyramids

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between different organisms.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Back

Primary consumers are organisms that eat producers (plants) and are the second level in a food chain.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy from one level to the next.

Front

What percentage of energy is typically transferred from one trophic level to the next?

Back

Typically, only about 10% of energy is transferred from one trophic level to the next.

Front

What is an omnivore?

Front

What is a carnivore?

Back

A carnivore is an organism that primarily eats other animals.

Front

What is a herbivore?

Back

A herbivore is an organism that primarily eats plants.

Front

What happens to energy as you move up the energy pyramid?

Back

As you move up the energy pyramid, the amount of energy decreases.

Front

What do the arrows in a food web represent?

Back

The arrows in a food web represent the direction of energy flow, pointing from the organism that is eaten to the organism that eats it.
