Which of the following choices refers to the rate of production of new biomass that would be available for consumption by bacteria,fungi,or animals?
A) Net primary productivity
B) Gross primary productivity
C) Secondary productivity
D) Net ecosystem productivity

Question

Quizplus · Accepted Answer

Net primary productivity is defined as the rate of production of new biomass by photosynthetic organisms, minus the rate of respiration by these same organisms. It represents the amount of biomass that is available for consumption by other organisms in the ecosystem, such as bacteria, fungi, and animals. Gross primary productivity, on the other hand, is simply the total amount of biomass that is produced through photosynthesis, without accounting for the energy that is used by the plants themselves in respiration. Secondary productivity refers to the production of biomass by organisms at higher trophic levels, such as herbivores and carnivores, and is not directly related to the rate of production of new biomass by primary producers. Net ecosystem productivity refers to the overall balance between carbon uptake and release in an ecosystem, and includes both primary productivity and other processes such as decomposition and carbon storage.
