a primary consumer is always a

• omnivore

• carnivore

• omnivore or herbivore

• herbivore

a producer always

• eats other producers

• gets energy from the sun

• is a herbivore

• is a plant

True or False. In this energy pyramid, the consumers on each level only get about 10 percent of energy that the trophic level before it has stored.

• True

• False

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

• 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. 

• energy amounts are the same at each trophic level

In this energy pyramid, which organisms have the most energy available?

• Producers

• Carnivores

• Herbivores

• Top Predator

Why are producers found at the base of the pyramid?

• They create all of the energy and therefore have the most energy of all of the trophic levels

• There are more plants than animals. 

• They begin the flow of energy in an ecosystem.

• All of these answers are correct.
