According 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:

  1. 1.54 million
  2. 5.46 million
  3. 3.50 million
  4. 0.78 million

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).
