If only 10% of an organism's energy is available for the next trophic level, what happens with the other 90% of the energy?

• It is destroyed after it is used up.
• It is used for life processes or lost as body heat.
• It remains for the next trophic level IF the predator consumes ALL of the organism.
• It is lost completely as body heat.

What makes an energy pyramid different than a food web or chain?

• It shows energy flowing from the top of the chain and downward. 
• The tropic levels are the opposite
• It shows the amount of energy in each trophic level
• It shows specific predator/prey relationships

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.
