Q. 37 A4.0( 4 Votes )

Explain why, a food chain usually cannot have more than three or four steps.

Answer :

10% energy transfer takes place from one trophic level to the next trophic level. Producers absorb one percent of sun’s energy to make food and then transfer 10% of it to the next trophic level and so on. There cannot be more than three or four steps in food chain because after that the energy availability to the organisms will be so less that the organism will not be able to survive with that less amount of energy available to them.
