Question

Match List I with List II:

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

Choose the correct answer from the options given below:

• A. A-II, B-III, C-I, D-IV
• B. A-III, B-I, C-IV, D-II
• C. A-I, B-III, C-II, D-IV
• D. A-III, B-IV, C-II, D-I

Answer 1

The Correct Option is B

The correct matching between List I and List II is as follows:

List I	List II
Robert May	Global species diversity at about 7 million
Alexander von Humboldt	Species-Area relationship
Paul Ehrlich	Rivet popper hypothesis
David Tilman	Long term ecosystem experiment using outdoor plots

Explanation:

• Robert May is known for his work on estimating global species diversity, which is around 7 million.
• Alexander von Humboldt introduced the concept of the species-area relationship.
• Paul Ehrlich proposed the "Rivet Popper Hypothesis," suggesting the ecological importance of species.
• David Tilman conducted long-term ecosystem experiments using outdoor plots to study biodiversity and ecosystem function.

Thus, the correct pairing is: A-III, B-I, C-IV, D-II.
