True or False: Organisms will always stay in the same trophic level. 

• True-- an organism's trophic level is permanent based on the species it is. 

• False-- the trophic level an organism belongs to is based on what it is consuming in the food chain. 

The diagram represents different levels of a marine food pyramid. Between which two levels is the greatest amount of energy transferred

• R and Q

• S and R

• T and S

• U and T

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.

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.

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

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

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