Question

the diagram below represents an energy pyramid.
at each successive level from e to h, the amount of available energy:
a. increases only
b. decreases only
c. remains the same
d. increases, then decreases

Explanation:

In an energy pyramid, energy transfer between trophic levels follows the 10% rule. As we move up each level (from producers at the base to top - level consumers), most of the energy (about 90%) is lost as heat or used for metabolic processes. So, only about 10% of the energy is passed on to the next level.

Answer:

B. decreases only
