| 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
A.A-III, B-I, C-IV, D-II
B.A-I, B-II, C-III, D-IV
C.A-I, B-III, C-IV, D-II
D.A-III, B-I, C-II, D-IV
Solution
Sol. [Key Concept: Matching biological concepts]
Productivity is the rate of biomass production.
Net primary productivity is the Gross primary productivity (GPP) minus respiration losses (R).
Gross primary productivity is the rate of production of organic matter during photosynthesis.
Secondary productivity is the rate of formation of new organic matter by consumers.
