The correct answer 10%. Only 10% of the total energy is transferred to the next trophic level.
<h3>Explanation:</h3>
While energy moving from the one trophic ;level to another is lost in many processes.
The transfer is not the 100% due to some reasons like the maintenance of that trophic level.
90 Percent of the produced energy is used in the reproduction of the organisms, their growth, in respiration , movement fighting and other life maintaining processes.
Hence only 10% energy is reached to next trophic level.
During the transfer of energy from one tropic level to the next tropic level around 90% of the total energy is lost in the metabolic processes in the form of heat. Hence only about 10% of the total energy can only be transferred from one tropic level to the next tropic level.
