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

 

Answers (1)

In any ecosystem, the number of trophic levels can go up to a maximum of five, and in that case, the food chain will look like the following:

Producer → Primary Consumer → Secondary Consumer → Tertiary consumer → Quaternary Consumer

Let us assume that the producer captures 100 units of energy. Out of this, the producer will use 90 units, and 10 units will be available for the primary consumer. Finally, just 0.001 unit will be available for the quaternary consumer, which is a negligible amount of energy.
Hence, more trophic levels are not possible in any ecosystem.
