Question

The length of food chain is limited to about 2 to 10 levels give reason

Answer 1

Answer:

Explanation:

Food chains are limited to 4-5 trophic levels because energy losses between trophic levels restrict the length of food chains and the biomass of higher trophic levels.

Answer 2

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.
