Question

How would you explain the paradox that the pyramid of biomass in sea is inverted because biomass of fishes exceeds that of phytoplankton?

Answer 1

Pyramid of energy is always upright, can never be inverted because when energy flows from a particular trophic level to the next trophic level, some energy is lost as heat at each step. 

Each bar in the energy pyramid indicates the amount of energy present at each trophic  level in the given time, however there are certain limitations of ecological pyramids such as it does not take into account the same species belonging to two or more trophic levels.

The pyramid of biomass in sea is inverted because biomass of fish exceeds that of phytoplankton and in this scenario the biomass of trophic level depends on the reproductive potential and the longevity of the member.

Marine environment have inverted biomass pyramids.

Phytoplankton has much less lifespan than fish. 

Answer 2

Answer:

Biomass is the amount of living organic matter. Pyramid of biomass is graphical representation of biomass sequence wise per unit area of different trophic levels.

Explanation:

Pyramid of biomass is inverted because;

Food chain in ocean- the biomass of zooplankton is greater than phytoplankton, the producer because of their small size and low mass. The predatory fish is much larger than zooplankton.

In aquaticecosystem producers are phytoplankton that has a short life span and turn over and have lower mass than zooplankton

The biomass of a trophic level is dependant on the longevity of members.
