Question

on average, how much of the available energy from one trophic level is transferred to the next trophic level in a food chain?
a 10%
b 25%
c 50%
d 75%

Explanation:

In an ecosystem, the energy transfer between trophic levels follows the 10% law. This law states that, on average, only about 10% of the energy available at one trophic level is transferred to the next trophic level. The rest of the energy is used for metabolic processes (like respiration), lost as heat, or remains undigested in waste.

Answer:

A. 10%
