NEET Botany (general) MCQ Question
Type: MCQ-numerical-Hard-Class 12
Alexander von Humboldt observed that species richness in a region increased with the explored area only up to a certain limit. If the species richness of a 100 square km area in a tropical region is 150 species, what would be the most plausible species richness in a 400 square km area, assuming the relationship holds and the limit is not yet reached?
A
300 species
B
450 species
C
600 species
D
750 species
Correct Answer
Option A
Detailed Explanation
The species-area relationship indicates that species richness increases with area but not linearly. Doubling the area does not double the species richness, so an increase from 100 to 400 square km is likely to show less than a fourfold increase in species richness.
