Vedclass · Answer

(A) In ecology, the biomass of an organism or a trophic level is defined as the total amount of living matter present at a given time.To ensure consistency and comparability, biomass is measured in terms of dry weight rather than fresh weight.Fresh weight includes the water content of the organism, which varies significantly and does not represent the actual organic matter available for energy transfer.Therefore, biomass is expressed as the dry weight of organisms per unit area.
