KCET · BIOLOGY · STD 12 - 13. Biodiversity and Conservation
Select the option from the following which is not a major characteristic feature of biodiversity hotspots.
- A Large number of species
- B Destruction of habitats
- C Abundance of endemic species
- D Large number of exotic species
Answer & Solution
Correct Answer
(D) Large number of exotic species
Step-by-step Solution
Detailed explanation
(D) Large number of exotic species,
A biodiversity hotspot is a biographic region that is both a significant reservoir of biodiversity and is threatened with destruction. The term biodiversity hotspot was coined by Dr. Norman Myers in 1998 who defined two criteria for an area to qualify as a biodiversity hotspot. It must contain at least 0.5% or 1,500 endemic species (species confined to that region).
