Question

Considering May’s global estimates, how many of the total species have been recorded?

(a) 1 percent

(b) 22 percent

(c) 10 percent

(d) 50 percent

This question was addressed to me in an online interview.

This key question is from Biodiversity topic in chapter Biodiversity and Conservation of Biology – Class 12

Answer 1

Right answer is (b) 22 percent

For explanation I would say: Robert McCredie May is a theoretical ecologist and promoter of science. He estimated that there are almost 7 million species globally. Considering May’s global estimates, only 22 percent of the total species have been recorded.
