Determining Biomass

APBIO-WV3SNE

When considering the biomass of a photosynthetic organism for energy transfer studies, why is it necessary to use the dry mass rather than the wet mass to determine productivity?

A

The wet mass can vary widely due to differing concentrations of minerals in soil.

B

The mass that is produced and added to the organism does not include the mass of water.

C

Water has no caloric value.

D

Water plays no role in primary productivity.
