Answer 2

Answer:

Hey mate here is ur answer......

Explanation:

1) Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.

2) The term megadiverse country refers to any one of a group of nations that harbor the majority of Earth's species and high numbers of endemic species. Conservation International identified 17 megadiverse countries in 1998. Many of them are located in, or partially in, tropical or subtropical regions.

3) India has tremendous biodiversity, genetic as well as of species and ecosystems. It contains over 7 per cent of the world's biodiversity on 2.5 per cent of the Earth's surface. ... Among amphibians found in India, 62% are unique to this country.

4) India, a megadiverse country with only 2.4% of the world's land area, accounts for 7-8% of all recorded species, including over 45,000 species of plants and 91,000 species of animals.

5) Walter G. Rosen

G. RosenThe term 'Biodiversity', coined by Walter G. Rosen in the year 1985 (Wilson, 1988) is a relatively new compound word of the longer version 'Biological Diversity', which was introduced by Lovejoy (1980) to express the number of species present in the community.

6) Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).

• includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).Genetic Diversity.

7) For example, a single plant may be considered as unit of alpha diversity ; a leaf as an area of point diversity ; a group of plants occurring together as an area of gamma diversity and the forest within which the plants are located as an area of epsilon diversity.
