In an energy pyramid, energy _________ as you move up the pyramid.

• increases

• decreases

• stays the same

• changes up and down

The diagram represents a pyramid of energy in an ecosystem.  Which level would most likely contain members of the plant kingdom?

• A

• B

• C

• D

The 10% rule states that 10% of energy moves from each trophic level to the next.

In the pyramid, if the producers level contains 1234 kilocalories, how many kilocalories are transferred to the primary consumer level?

• 123.4

• 1.234

• 1234

• 1234

The 10% rule states that 10% of energy moves from each trophic level to the next.

What type of diagram shows the amount of energy that moves from one trophic level to another in a food web?

• Energy Pyramid

• Food Web

• Ecosystem

• Food Chain

The diagram is intended to show relationships in an ecosystem. What do the arrows represent?

• The direction of population migration

• Differences in dietary habits

• Progressively smaller organisms

• The direction of the energy flow

The diagram represents different levels of a marine energy pyramid.

Between which two levels is the greatest amount of energy transferred?

• R and Q

• S and R

• T and S

• U and T

A pyramid shape is used to show the amount of available energy at each trophic level because ...

• energy amounts are the same at each trophic level.

• energy decreases as you go up the food chain, just like the pyramid shape gets smaller as you go up. 

• energy increases up the food chain just like the pyramid shape gets smaller as you go up.
