Best answer
The correct option is (b) By the help of pyramid of biomass

The best explanation: A pyramid of biomass is a more accurate indication of how much energy is passed at each trophic level. Biomass is the mass of living material in each organism multiplied by the total number of organisms in that trophic level.
