Question

Algae are at the first trophic level. Flagfish are in the second trophic level. When a Flagfish eats algae, what percent of energy is transferred from the first to the second trophic level?
a. 5%
b. 10%
c. 75%*****
d. 90%

Answer 1

b. 10% of energy is transferred from the first to the second trophic level.

Explanation:

In trophic level flow of energy is one way, only a small amount of energy get transferred with the organism. A large amount of energy gets dissipated in life processes like respiration, reproduction and digestion. The energy is also released as waste product. Thus, only ten per-cent of the total energy is present in the organism.

The energy transfer does not depend on the number of trophic levels.

Each trophic level receives the 10% energy from the previous trophic level as when algae is eaten by flagship.
