Question

why food chains cannot have more than four trophic levels?
give reason.​

Answer 1

Answer:

The different feeding positions in a food chain or web are called trophic levels. Generally, there are no more than four trophic levels because energy and biomass decrease from lower to higher levels. Food chains are limited to 4 trophic levels because less and less energy is available at higher trophic levels.
