Question

Measurement of biomass in terms of dry weight is more accurate. Why?

Answer 1

Part 1: Definition of biomass
Biomass represents the mass of living tissue over a particular area in a given time period.

Part 2: Calculation of biomass
Biomass can be expressed in the terms of wet weight or dry weight. Dry weight is the weight of the organism after all the water is removed. It is usually expressed as $g/m^2$.

Part 3: Significance of dry weight
Biomass in terms of dry weight is more accurate as wet weight may vary based on the physiological and environmental conditions of the species. Hence, dry weight is considered to be a better alternative to provide insights into ecosystem functioning and productivity.
