Open in App
Solution
The correct option is D Size of the organisms
In the construction of pyramid of biomass only dry weight of the organisms at each trophic level is considered as an accurate measure of biomass of the organisms. The size of the organism would more or less indicate the biomass, but it is the dry weight - that is the weight of the organism devoid of the moisture content in it, that is the measure of biomass.
