Energy Transfer/Food Web

Front

What is energy transfer?

Back

Energy transfer is the process by which energy moves from one system or organism to another, often through food chains or food webs.

What are producers in an ecosystem?

Back

Producers are organisms, like plants and algae, that can make their own food through photosynthesis, serving as the base of the food web.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow.

Front

What is a primary consumer?

Back

Primary consumers are herbivores that eat producers (plants) to obtain energy.

Front

What is a secondary consumer?

Back

Secondary consumers are organisms that eat primary consumers; they can be carnivores or omnivores.

Front

What is the pyramid of energy?

Back

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

Front

How much energy is typically passed from one trophic level to the next?

Back

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

Front

What happens to the remaining energy in the pyramid of energy?

Back

The remaining energy (about 90%) is lost as heat or used for metabolic processes.

Front

Who has the least amount of energy in a food web?

Back

The top predators, such as polar bears, have the least amount of energy compared to producers.

Front

What is a tertiary consumer?

Back

Tertiary consumers are organisms that eat secondary consumers and are often top predators in the food web.
