The typical percentage of loss of energy in transfers from one trophic level to the next is about

a. 35%
b. 60%
c. 1%
d. 90%
e. 5%

D. 90%

Explanation:

When energy flows in a food chain, it is observed that the amount of energy flow decreases with successive trophic levels.It is generally observed that approximately 90% of the energy available at a trophic level is used up and only remaining 10 % is transferred to the next .This is termed as ten percent law. Thus, we can say that 90% of energy is lost when the energy is transferred from one trophic level to another.
