Question

1. according to the 10% rule, how much energy is lost as you move from one trophic level to the next?

a. 10% b. 25%
c. 50% d. 90%

Explanation:

The 10% rule in ecology states that only about 10% of the energy is passed on to the next trophic level. So the energy lost is \(100\% - 10\%=90\%\).

Answer:

d. 90%
