Options

  1. A(A)-(III), (B)-(I), (C)-(II), (D)-(IV)
  2. B(A)-(II), (B)-(III), (C)-(I), (D)-(IV)
  3. C(A)-(III), (B)-(II), (C)-(I), (D)-(IV)
  4. D(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Correct answer

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

Step-by-step solution

Gross primary productivity (GPP) of an ecosystem is the rate of production of organic matter during photosynthesis. Therefore, (A) matches with (III). Net primary productivity (NPP) is the available biomass for the consumption to heterotrophs (herbivores and decomposers). Therefore, (B) matches with (II). Secondary productivity is defined as the rate of formation of new organic matter by consumers. Therefore, (C) matches with (I). Respiratory loss (R) is the difference between gross primary productivity and net pri
