-
B
GPP and NPP are identical measures of the total solar energy converted to biomass.
-
C
NPP is the energy remaining from GPP after producers have accounted for their own metabolic needs through respiration.
-
D
GPP is the rate of biomass accumulation by consumers, whereas NPP is the rate for producers.
