Explanation:

Grasslands go by many names. In the U.S. Midwest, they're often called prairies. In South America, they're known as pampas. Central Eurasian grasslands are referred to as steppes, while African grasslands are savannas. What they all have in common are grasses, their naturally dominant vegetation. Grasslands are found where there is not enough regular rainfall to support the growth of a forest, but not so little that a desert forms. In fact, grasslands often lie between forests and deserts. (See grassland photos.)

Depending on how they’re defined, grasslands account for between 20 and 40 percent of the world's land area. They are generally open and fairly flat, and they exist on every continent except Antarctica, which makes them vulnerable to pressure from human populations. Threats to natural grasslands, as well as the wildlife that live on them, include farming, overgrazing, invasive species, illegal hunting, and climate change.

At the same time, grasslands could help mitigate climate change: One study found California's grasslands and rangelands could store more carbon than forests because they are less susceptible to wildfires and drought. Still, only a small percentage—less than 10 percent—of the world's grassland is protected.

Explanation:

A grassland is an area of land that mostly contains grasses. There are wild grasses, and there may be some trees. Several parts of the world have grasslands. Grasslands are found in Africa, North America, Central Asia, South America, and near the coasts of Australia.[1] The largest grasslands are in East Africa. Grasslands with a few scattered trees are called savannas. Others are called prairies or steppes.

Little rain falls in a grassland biome. Between 25 and 75 cm of rain falls each year, which makes the weather in these savannas hot and sunny in the summer and cool in the winter months.

Types are:-

a)Tropical and subtropical :-

These grasslands are classified with tropical and subtropical savannas and shrublands as the tropical and subtropical grasslands, savannas, and shrublands biome. Notable tropical and subtropical grasslands include the Llanos grasslands of South America.

b)Temperate :-

Mid-latitude grasslands, including the prairie and Pacific grasslands of North America, the Pampas of Argentina, Brazil and Uruguay, calcareous downland, and the steppes of Europe. They are classified with temperate savannas and shrublands as the temperate grasslands, savannas, and shrublands biome. Temperate grasslands are the home to many large herbivores, such as bison, gazelles, zebras, rhinoceroses, and wild horses. Carnivores like lions, wolves and cheetahs and leopards are also found in temperate grasslands. Other animals of this region include: deer, prairie dogs, mice, jack rabbits, skunks, coyotes, snakes, fox, owls, badgers, blackbirds (both Old and New World varieties), grasshoppers, meadowlarks, sparrows, quails, hawks and hyenas.

c)Flooded:-

Grasslands that are flooded seasonally or year-round, like the Everglades of Florida, the Pantanal of Brazil, Bolivia and Paraguay or the Esteros del Ibera in Argentina, are classified with flooded savannas as the flooded grasslands and savannas biome and occur mostly in the tropics and subtropics.

Watermeadows are grasslands that are deliberately flooded for short periods

d)Montane:-

High-altitude grasslands located on high mountain ranges around the world, like the Páramo of the Andes Mountains. They are part of the montane grasslands and shrublands biome and also constitute tundra.

e)Tundra grasslands:-

Similar to montane grasslands, polar Arctic tundra can have grasses, but high soil moisture means that few tundras are grass-dominated today. However, during the Pleistocene glacial periods (commonly referred to as ice ages), a freezing grassland known as steppe-tundra or mammoth steppe occupied large areas of the Northern Hemisphere. These areas were very cold and arid and featured sub-surface permafrost (hence tundra) but were nevertheless productive grassland ecosystems supporting a wide variety of fauna. As the temperature warmed and the climate became wetter at the beginning of the Holocene much of the mammoth steppe transitioned to forest, while the drier parts in central Eurasia remained grassland, becoming the modern Eurasian steppe.

f)Desert and xeric :-

Also called desert grasslands, this is composed of sparse grassland ecoregions located in the deserts and xeric shrublands biome.

Conclusion

The African grasslands contains many animal species that all contribute and affect each other in the ecosystem. Starting with producers such as grass, acacia trees and other shrubbery and then the consumers that eat it. This is a very important part of the worlds ecosystem because if one species is removed than every other species would suffer. All the organisms in this biome are dependent upon each other. This is why the African grasslands is a large and very important biome. We could protect these trees by starting a petition to stop cutting down these trees, which will let them replenish their populations, and will provide habitat for the local wildlife. The punishment for hunting black rhinoceros should be more severe, and if somebody is caught selling their horns on the black market, they should at least be sentenced to life in prison.

Hope it will help for you.....
