Question

An area is declared as hot spot, when

• A. It has 1500 or more endemic species and 75% of its original habitat is lost.
• B. It has 1500 or more vertebrate species and 75 of its original habitat is lost.
• C. It has more than 2000 species of plants.
• D. Most of the species inhabiting the area is facing the risk of extinction.

Answer 1

The correct option is A It has 1500 or more endemic species and 75% of its original habitat is lost.

The large areas which contain exceptional concentrations of plant endemism and are experiencing very high rates of habitat loss are called ecological hot spots. These are also known as biodiversity hot spots. 2.3% of the Earth's land surface is represented by them. Currently, 36 biodiversity hot spots exist in the world. An area must meet two strict criteria for becoming an ecological hotspot. Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as "endemic" species), Have lost at least 70 percent of its primary native vegetation.

So, the correct answer is 'It has 1500 or more endemic species and 75% of its original habitat is lost.'.
