Ecology Test review

The diagram below shows an energy pyramid for an aquatic ecosystem.

• The organisms at the top of the pyramid are the most efficient feeders.

• The organisms at the top of the pyramid have the largest population sizes.

• The organisms at the top of the pyramid need only a small amount of energy for their metabolism.

• The organisms at the top of the pyramid receive only a small fraction of the energy that originally enters the system.
