NEET Botany Biodiversity Patterns MCQ Question
If 22% of the total species have been recorded globally, and India's share of the global species diversity is 8.1%, how many total species can be estimated globally if India has recorded approximately 90,000 species?
5,000,000
2,500,000
1,000,000
10,000,000
Correct Answer
Detailed Explanation
If India has recorded 90,000 species, which is 8.1% of its estimated total species (90,000 / 0.081), this approximates to 1,111,111 species in India. Since globally only 22% are recorded, the total global species estimate would be 1,111,111 / 0.22 = 5,050,505, which rounds to option A.
