Which of the following ecological terms describes the available biomass for the consumption to heterotrophs (herbivores and decomposers) in an ecosystem?

Options

  1. AGross primary productivity
  2. BNet primary productivity
  3. CSecondary productivity
  4. DRespiration losses

Correct answer

B. Net primary productivity

Step-by-step solution

Gross primary productivity (GPP) is the rate of production of organic matter during photosynthesis. A considerable amount of GPP is utilized by plants in respiration (R). The remaining biomass, which is the net primary productivity (NPP), is the available biomass for the consumption to heterotrophs (herbivores and decomposers). Secondary productivity is the rate of formation of new organic matter by consumers. Answer: Net primary productivity
