| C. Gross primary productivity | III. Rate of biomass production |
| D. Secondary productivity | IV. Rate of production of organic matter during photosynthesis |
Choose the correct answer from the options given below :
Options
- AA-III, B-I, C-IV, D-II
- BA-I, B-II, C-III, D-IV
- CA-I, B-III, C-IV, D-II
- DA-III, B-I, C-II, D-IV
Correct answer
A. A-III, B-I, C-IV, D-II
Step-by-step solution
Productivity is defined as the rate of biomass production.
Gross primary productivity (GPP) of an ecosystem is the rate of production of organic matter during photosynthesis.
Net primary productivity (NPP) is the gross primary productivity minus respiration losses (), which is the available biomass for the consumption to heterotrophs.
Secondary productivity is defined as the rate of formation of new organic matter by consumers.
Therefore, the correct matching is A-III, B-I, C-IV, D-II.
Answer: A-III, B-I, C-IV, D-II
