<u>a. The more energy the organism requires, the more efficient the energy transfer</u>.
Explanation:
As the transfer of energy takes place in an ecosystem when the organism is consumed completely and thus when transferring the energy from one trophic level to another level the amount, of energy, has to be of larger quantities and thus the energy transfer will be effective.
Due to the fact that the energy is lost in the form of heat and thus the conversion of energy takes place gradually n the tropics and food web.
