Question:
Describe different types of grasslands. [V. Imp.]
Answer:
Different types of grasslands are:
- Tropical grasslands
- Temperate grasslands
- Thorny bushes
- Tropical grasslands. This type of vegetation grows in the areas of moderate to low amount of rainfall. The grass here can grow very tall, about 3 to 4 metres in height. Savannah grasslands of Africa are of this type. Common animals found here are elephants, zebras, giraffes, deer, leopards etc.
- Temperate grasslands. This type of vegetation is found in the mid-latitudinal zones and in the interior part of the continents. Grass here is usually short and nutritious. Common animals found in this region are wild buffaloes, bisons, antitopes etc.
- Thorny bushes. These are found in the dry desert like regions. Tropical deserts are located on the western margins of the continents, which are characterised by searce vegetation.
Vegetation in the polar regions is also limited. Only mosses, lichens and very small shrubs are found here. It grows during the very short summer. This is called Tundra type of vegetation. Polar animals have thick fur and thick skin which protect them from the cold climate conditions, for example, seal, walruses, musk-oxen, Arctic owl, etc.
