Match the types of ecological energy productivity in Group 1 with their respective definitions in Group 2.
| Group 1 | Group 2 |
|---|---|
| (P) Net primary productivity | (i) Total amount of energy produced by autotrophs |
| (Q) Gross primary productivity | (ii) Amount of energy stored by autotrophs after respiration |
| (R) Net productivity | (iii) Net gain of energy by the consumers after energy loss |
| (S) Secondary productivity | (iv) Unused amount of energy after consumption by heterotrophs |
(A) P−iii, Q−ii, R−iv, S−i
(B) P−ii, Q−i, R−iii, S−iv
(C) P−ii, Q−i, R−iv, S−iii
(D) P−iv, Q−i, R−ii, S−iii
Answer: (B) P−ii, Q−i, R−iii, S−iv
Explanation:
Net primary productivity is the energy stored after respiration (ii), gross primary productivity is the total energy produced (i), net productivity is the energy gained after losses (iii), and secondary productivity is the unused energy after consumption (iv).
