-
Groundnut
-
Rice
-
Maize
-
Mango
Which region is rich in species diversity?
-
North Pole
-
Temperate region
-
Tropical region
-
South Pole
Species diversity increases towards the equator. The two main reasons are phylogenetic niche conservatism and ecological productivity. The relatively high temperatures in the tropics generate and maintain high diversity. However, the tropical rainforests in developing countries are getting cleared nowadays, which is leading to a great loss of biodiversity.
Indian share in global species diversity is about
-
8%
-
6%
-
4%
