What do trophic pyramids demonstrate about the flow of energy in an ecosystem?

• The amount of energy available to each organism decreases as it flows through the ecosystem.

How do trophic pyramids get their shape?

• Trophic pyramids get their shape from the loss of energy that happens at each stage.

• Trophic pyramids get their shape from the types of organisms that are represented in the pyramid.

• Trophic pyramids get their shape because a pyramid is the easiest shape to represent a food web.

• Trophic pyramids get their shape from the number of organisms at each point on a food chain.
