Question

what percentage of energy is typically transfered to the next trophic level?
a. 10%
b. 20%
c. 50%
d. 90%

Explanation:

In an ecosystem, when energy is transferred from one trophic level to the next, only about 10% of the energy is typically passed on. This is known as the 10% rule. The rest of the energy is lost as heat during metabolic processes (like respiration) or used for the organism's own life - sustaining activities.

Answer:

A. 10%
