Grassland is an area which mostly contains grasses. There may be some trees and some wild grasses. Africa, Central Asia, North America, South America and near the coasts of Australia we could find these grasslands.
The temperate grasslands are the predominant vegetation in this biome which consists of grass and/or shrubs. The grasslands in East Africa are the largest grasslands. If these grasslands contain few scattered trees, then it is known as savannas. Others are also called prairies or steppers. The chalk grasslands in southern England are quite short with small delicate flowers. The grass in North America is quite tall. This provides a shelter or a cover for the smaller animals to live there which would also increase the number of the species living there. In some grassland woody plants, trees or shrubs may occur. A complex mat is formed by the root system of the perennial grasses that hold the soil in place. Before the tall grass was replaced by the modern crops in North America, the native ecosystem was tallgrass prairie. Morine material was dropped by the retreating glaciers about 10,000 years ago and wind –dropped loess and the organic matter got accumulated. This made the soil. In Africa, the temperate grasslands are called velds.
Thus, option (C) is correct.
In the grasslands, there is very little rainfall between 25 cm and 75 cm every year. This makes the weather here hot and sunny in the summer and cools in the months of winter.
