Which one of the following statements about biodiversity is not correct?

Options

  1. AThe term 'biodivessity' was coined by Walter G. Rosen in 1986.
  2. BThe term 'biodiversity hotspots' was coined by Norman Myers in 1988.
  3. CThe regions having richest biodiversity are called 'biodiversity hotspots'.
  4. DMore than 100 hotspots of biodiversity are identified in the world.

Correct answer

D. More than 100 hotspots of biodiversity are identified in the world.

Step-by-step solution

A hotspot is a natural habitat that has at least more than 0.5 % of total vascular plants as endemic species and is under threat by human activities. There are 36 biodiversity hotspots on our planet, and these areas are dazzling, unique, and full of life. Plants, animals, and other living organisms that populate these places are rare and many of them are only found in these specific geographic areas. It covers only 2.3 % of the earth surface but is a habitat for 77 % of the world's species.
