Grassland ecosystems are terrestrial ecosystems dominated by grasses and other herbaceous plants, with relatively few trees. They occur in regions where rainfall is insufficient to support dense forests but adequate to sustain grasses. Major types include tropical grasslands, such as savannas, and temperate grasslands, such as prairies, steppes and pampas. Grasslands are found across large areas of Africa, Asia, Australia, North and South America, and parts of India. They support diverse plants, animals and microorganisms and provide important ecological and economic services. Grasslands are important for maintaining biodiversity. They provide habitat and food for a wide variety of herbivores, carnivores, birds, insects, reptiles and microorganisms. Animals such as deer, antelope, bison, wild horses and various grassland birds depend on these habitats. In India, grasslands support species such as blackbuck, chinkara, Indian wolf, great Indian bustard and several migratory birds. The presence of different organisms creates complex food chains and contributes to ecological balance. Grasslands play a significant role in maintaining soil fertility and preventing soil erosion. Dense networks of grass roots bind soil particles together and reduce the loss of topsoil caused by wind and water. When grasses and other plants die, their organic matter decomposes
