Trophic-Level Transfer Efficiency Averages About

Question

Trophic-level transfer efficiency averages about
A)1%.
B)25%.
C)33%.
D)10%.
E)0.1%.

Accepted Answer

Trophic-level transfer efficiency, which measures the amount of energy that is transferred from one trophic level to the next, averages about 10%. This reflects the general rule that only about 10% of the energy from one trophic level is passed on to the next level due to energy losses primarily from metabolic processes and heat.
