Answer 1

Answer: As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller.

Explanation: While energy can not be created or destroyed is it released as heat within each level. Approximately only 10% of energy is passed from one level to the next.
