Question: 138. Match List I with List II
| List I | List II |
|---|---|
| A. Robert May | I. Species-Area relationship |
| B. Alexander II. 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 |
Choose the correct answer from the options given below:
(1) A-II, B-III, C-I, D-IV
(2) A-III, B-I, C-IV, D-II
(3) A-I, B-III, C-II, D-IV
(4) A-III, B-IV, C-II, D-I
Answer: Option (2)
Explanation:
Robert May provided an estimate of global species diversity and suggested that the total number of species on Earth is about 7 million, so A is matched with III.
Alexander von Humboldt proposed the species–area relationship, which explains how species richness increases with increasing geographical area, hence B is matched with I.
Paul Ehrlich proposed the rivet popper hypothesis, which explains the effect of species loss on ecosystem stability, therefore C is matched with IV.
David Tilman is known for conducting long-term ecosystem experiments using outdoor plots to study biodiversity and ecosystem functioning, so D is matched with II.
Thus, the correct matching is A-III, B-I, C-IV, D-II.
