Answer 2

Answer:

In an ecosystem, the number of trophic levels is limited as they cannot be more than 3 to 4 trophic levels.

This is because the "amount of energy flow" decreases with the successive trophic level. With each level transfer, only 10% of the energy is transferred from "one trophic level" to the "next trophic level" and hence the levels in the food chain must be limited.

Then, the trophic level of an organism is the number of steps it is from the start of the chain.
