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

About how much percent of energy is passed on from one organism to to the next on an energy pyramid?

• 100 percent of all energy gets passed
• 45 percent of all energy gets passed
• 10 percent of all energy gets passed
• 0 percent of all energy gets passed

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.
