B. (A)-(III), (B)-(I), (C)-(II), (D)-(IV)

Step-by-step solution

Gross primary productivity (GPP) of an ecosystem is the rate of production of organic matter during photosynthesis. A considerable amount of GPP is utilized by plants in respiration, which is the respiration loss (R). Net primary productivity (NPP) is the gross primary productivity minus respiration losses (GPP - R = NPP). It is the available biomass for the consumption of heterotrophs (herbivores and decomposers). Secondary productivity is defined as the rate of formation of new organic matter by consumers. Theref
