Abstract
Amazon has hot temperature (26oC to 30oC) throughout year, and availability of water is also there throughout the year. Amazon has 3,000 species of fishes, 450 species of reptiles, 1300 species of birds and 430 species of mammals. North Canada has temperature range (40oC to 25oC) It has 1389 species of fishes, 48 species of reptiles, 986 species of birds, and 200 species of mammals. Thar Desert Temperature range (5oC to 45oC) and water not available, 142 species of fishes, 350 species of birds, 35 species of reptiles and 60 species of mammals. So, we can conclude biodiversity is proportional to low temperature and availability of water.
