Question

Quizplus · Accepted Answer

The 10% rule states that approximately 10% of the energy available in one trophic level is incorporated into the next trophic level. This is due to energy loss through processes such as cellular respiration, heat loss, and incomplete digestion. Therefore, only a small fraction of the energy from the original food source is available to higher trophic levels.
