Question

Quizplus · Accepted Answer

The maximum number of trophic levels in an ecosystem is limited by the available energy, favorable temperatures, and available water. Energy is lost as heat at each trophic level, so the number of levels is limited by the amount of energy available at the base of the food chain. Favorable temperatures are also necessary for the survival of organisms at each trophic level. Water is essential for all life, and its availability can limit the number of trophic levels in an ecosystem.
