A) GPP is greater than NPP because of the metabolic process of photosynthesis.
B) GPP is greater than NPP because of the metabolic process of respiration.

E) There is no significant difference between GPP and NPP.

Question

Quizplus · Accepted Answer

Gross Primary Productivity (GPP) is the total amount of energy captured by photosynthesis, while Net Primary Productivity (NPP) is the energy remaining after accounting for the energy used in respiration. Therefore, GPP is greater than NPP because some energy is used in the metabolic process of respiration.
