Standing crop is determined by _____ productivity.

Question

Quizplus · Accepted Answer

Standing crop refers to the amount of living organic material (biomass) present in an ecosystem at a particular point in time. Net primary productivity (NPP) refers to the rate at which energy is stored in organic matter after accounting for the energy used in respiration by plants during photosynthesis. Therefore, the amount of standing crop in an ecosystem is determined by NPP. Gross primary productivity (GPP) refers to the total rate of photosynthesis, including the energy used in respiration, while net secondary productivity (NSP) and gross secondary productivity (GSP) refer to the amount of biomass produced by heterotrophic organisms and the total rate of biomass production by the ecosystem's consumers, respectively. Hence, the best choice for determining standing crop is net primary productivity.
