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.
