The number of trophic levels in an ecosystem are limited. Comment.

In the ecosystem in each successive trophic level, there is a 10 percent transfer of energy. As the number of trophic levels starts to increase in an ecosystem the energy starts to decrease as well. So, after a few trophic levels, the energy becomes zero and thus the trophic level succession stops and therefore, the number of trophic levels in an ecosystem are limited.
