A student measures wet masses of plants and herbivores and uses them to calculate biomass transfer. The herbivores have a much higher water percentage than the plants.
How would using wet mass instead of dry mass affect the calculated percentage transfer?
It would underestimate it because herbivore water adds relatively more mass.
It would overestimate it because plant water adds relatively more mass.
It would overestimate it because herbivore water adds relatively more mass.
It would underestimate it because plant water adds relatively more mass.
