• 10%
• 100%
• 1000%

Why is a shark a carnivore.

• because it eats seaweed
• because it eats dead animals
• because it eats sand 
• because it eats other animals

In the energy pyramid here, how much of the energy in each level gets lost as heat or used by the organism for survival?

• 80%
• 90%
• 10%
• 20%
