C)NPP - GPP = R
D)NPP - R = GPP

Question

Quizplus · Accepted Answer

GPP (Gross Primary Productivity) is the total amount of energy produced by photosynthesis in an ecosystem, while R (Respiration) is the amount of energy used by the ecosystem's plants and animals. NPP (Net Primary Productivity) is the amount of energy remaining after respiration is subtracted from GPP. Therefore, the correct formula for productivity is GPP - R = NPP. Option B is the correct choice as it shows that the amount of energy left after respiration has been taken into account, which is NPP.
