Match the Column I with Column II:

A-3,B-2, C-1,D-4

The correct answer is Option (2) - A-3, B-2, C-1, D-4

A. Term biodiversity - 3. Edward Wilson.Edward Wilson, the sociobiologist, popularized the term "biodiversity" to describe the combined diversity at all levels of biological organization.

B. Communities with less species - 2. Less stable. Communities with fewer species tend to be less stable because they have limited redundancy and are more susceptible to disruptions or changes in environmental conditions.

C. Communities with more species - 1. More stable. Communities with a higher number of species tend to be more stable because they have a greater variety of ecological roles and interactions, making them more resilient to disturbances.

D. Rivet popper hypothesis - 4. Paul Ehrlich .The "Rivet popper hypothesis" was proposed by Paul Ehrlich, an American biologist, and it suggests that ecosystems are like aeroplanes, and the removal of individual species can be compared to popping rivets from the plane's structure, leading to potential system failure (ecosystem functioning may or may not be compromised, depending on which species are being lost).
