NEET 2026 (Phase 1) · BiologyPrevious Year Question
Match List I with List II : List I A. Productivity B. Net primary productivity C. Gross primary productivity D. Secondary productivity List II I. Gross primary productivity minus respiration losses II. Rate of formation of new organic matter by consumers III. Rate of biomass production IV. Rate of production of organic matter during photosynthesis Choose the correct answer from the options given below :
- 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
Correct Answer
(A) A-III, B-I, C-IV, D-II
Solution & Explanation
Answer: (A) Productivity is the rate of biomass production (III); NPP is GPP minus respiration losses (I); GPP is the rate of production of organic matter during photosynthesis (IV); secondary productivity is the rate of formation of new organic matter by consumers (II). This gives A-III, B-I, C-IV, D-II, option (1)/(a). All four definitions are stated verbatim in NCERT section 12.2. NCERT Reference: Ch 12, p.207 — “rate of formation of new organic matter by”
