Food Webs & Energy Pyramids #3

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 between them.

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy at different trophic levels in an ecosystem, illustrating how energy decreases as it moves up the pyramid.

What are producers in a food web?

Back

Producers are organisms, like plants, that create their own food through photosynthesis and form the base of the food web.

What are primary consumers?

Back

Primary consumers are herbivores that eat producers (plants) and are the second level in the energy pyramid.

Front

What are secondary consumers?

Back

Secondary consumers are carnivores that eat primary consumers and are the third level in the energy pyramid.

Front

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

Back

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

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the organism's role in the flow of energy, such as producer, primary consumer, or secondary consumer.

How does energy decrease in an energy pyramid?

Back

Energy decreases as you move up the energy pyramid because energy is lost as heat and through metabolic processes at each trophic level.

What role do decomposers play in a food web?

Back

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