Which of the Following Choices Refers to the Rate of Production

Question

Which of the following choices refers to the rate of production of biomass by heterotrophs?
A) Biomass
B) Net primary productivity
C) Net ecosystem productivity
D) Secondary productivity

Accepted Answer

Secondary productivity refers to the rate of production of biomass by heterotrophs, such as herbivores and carnivores, in an ecosystem. It is the energy stored in these consumers' bodies after they have consumed and processed the primary producers (plants or algae) through photosynthesis. The other options are not directly related to this concept - biomass refers to the total weight of living organisms in an area, net primary productivity refers to the rate of production of biomass by photosynthesis, and net ecosystem productivity refers to the balance of carbon uptake and carbon loss in an ecosystem.
