Question

1. Is it possible to produce the same biomass per unit time at a higher and a lower trophic level? Clearly explain your answer.

Answer 1

No, It is not possible to produce the same biomass per unit time at a higher and a lower trophic level. Because biomass decreases as trophic level Increases. Higher the trophic level lower the biomass. The main reason behind this is that the biomass pyramid is similar to the food pyramid that is used to demonstrate the trophic levels in an ecosystem. The first explanation for this Is that not all energy is fairly passed up the food chain. The combination of the reduced amount of energy available in food with the increased amount of energy needed to produce the food leads to less species at the top level that can survive, thereby reducing the biomass of that trophic level.
