Question : The table shows the number of species of birds seen in some places. Colombia - 1400 New York - 105 Greenland - 56 India - 1200 South America (Amazon) - 1300 What could be the reason for the difference in the number of bird species present? Justify your answer.

Answer»

Solution :The species diversity decreases as we move away from the equator to the polar REGION. A LATITUDINAL range of `23.5^(@)N` to `23.5^(@)S` has more species when compared to the temperate or polar regions. As in the table, Colombia, India and Amazon areas are seen in trophical region. So they have more species. NEW York and Greenland are seen in `41^(@)Nand71^(@)N` LATITUDE respectively. So we can see a decrease in the NUMBER of species. This may be due to the availability of more solar energy in the trophical regions.
