Biology · BIODIVERSITY AND CONSERVATION
हिन्दीAccording to Robert May's global estimates, the total number of species present on Earth is approximately 7 million. If recorded species represent about 22% of this estimate, the number of species yet to be discovered globally is roughly:
Correct answer · Option 2
5.46 million
Explanation
Recorded species are \( 22\% \) of 7 million = 1.54 million; therefore, undiscovered species are \( 7 - 1.54 = 5.46 \) million (or \( 78\% \) of 7 million).
