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.
This would be Mitosis.
Mitosis results in two diploid cells.
Meiosis, on the other hand, results in four haploid cells.
