Question

To find the gross primary productivity of a region, A. subtract energy lost to respiration from the GPP B. multiply the GPP by energy lost to respiration C. add energy lost to respiration to the NPP D. multiple the GPP by the NPP

Answer 1

The correct answer is C. add energy lost to respiration to the NPP. Gross primary productivty refers to the total amount of carbon produced by a region, which accounts for both metabolic compounds (which will be consumed) and structural compounds (which will endure as they represent the structural basis of the organism).
