            NOTES-

            Grasslands include tropical and temperate grasslands. Tropical grasslands grow in the
            areas of moderate to low amount of rainfall. Savannah grasslands of Africa present a
            suitable example of these types of grasslands. Animals like elephants, zebras, giraffes,
            dear are commonly found here.


            Temperate grasslands are found in the mid-latitudinal zones and in the interior part of the
            continents. Short and nutritious grass in found here. Common animals are buffaloes,
            bison, antelopes etc.


            Thorny bushes are found in the dry deserts. Here, vegetation cover is scarce because of
            poor rain and scorching heat.


            Polar regions are cold and their natural vegetation is limited here. Only mosses, lichens
            and very small shrubs are found here. Vegetation found in the polar regions is called
            Tundra type of vegetation. Seal, walruses, musk-oxen, Arctic owl etc. are common here.
