Question

what happens to the amount of energy available as you move up trophic levels? decreases increases

Explanation:

As you move up trophic levels, energy is lost. This is due to the 10% rule in ecology, where only about 10% of the energy from one trophic level is passed on to the next. Energy is used for metabolic processes (like respiration), and some is lost as heat. So, the amount of energy available decreases as you move up trophic levels.

Answer:

A. decreases
