Correct answer: D). Energy decreases from bottom to top because some is used at each level for life processes.
The pyramid of matter and energy in the ecosystem tells that when energy flows from one trophic level to another trophic level, then some amount of energy is always lost as a heat, which is lost to the atmosphere and it never comes back.
