Choose the correct answer from the options given below. (NEET 2024)
| List I | List II |
|---|---|
| A. Robert May | I. Species-Area relationship |
| B. Alexander von Humboldt | II. Long term ecosystem experiment using out door plots |
| C. Paul Ehrlich | III. Global species diversity at about 7 million |
| D. David Tilman | IV. Rivet popper hypothesis |
Answer: (A) A-III, B-I, C-IV, D-II. Answer: (a) A-III, B-I, C-IV, D-II Solution: Robert May placed the global species diversity estimate at about 7 million (A-III); Alexander von Humboldt described the species-area relationship (B-I); Paul Ehrlich proposed the rivet popper hypothesis (C-IV); and David Tilman conducted long-term ecosystem experiments using outdoor plots (D-II).

Correct Answer
(A) A-III, B-I, C-IV, D-II
Solution & Explanation
Answer: (a) A-III, B-I, C-IV, D-II Solution: Robert May placed the global species diversity estimate at about 7 million (A-III); Alexander von Humboldt described the species-area relationship (B-I); Paul Ehrlich proposed the rivet popper hypothesis (C-IV); and David Tilman conducted long-term ecosystem experiments using outdoor plots (D-II). Only option (a) matches all four correctly.
