Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A-III, B-IV, C-I, D-II
(A) Stable community is resistant to invasion by alien species — this matches (III) David Tilman. His long-term outdoor plot experiments showed that plots with more species had less year-to-year variation in total biomass. This is the sign of a stable community, one that also resists invasion by alien species.
(B) Species-Area relationships — this matches (IV) Alexander von Humboldt. While exploring the South American jungles, he saw that species richness rose with the explored area, but only up to a limit.
(C) Popularised the term biodiversity — this matches (I) Edward Wilson. This sociobiologist made the term biodiversity widely used for the variety at all levels of life.
(D) Placed the global species diversity at about 7 million — this matches (II) Robert May. His estimate is a conservative and scientifically sound one, far below the extreme guesses of 20 to 50 million.
