Explanation The difference in the climate and the vegetation of three types of grasslands are as follows: No Characteristics Tropical grassland Temperate grassland Cold grassland 1 Climate The tropical grassland face extreme hot and dry climate. In such grasslands, the winters are bitter and cold while the summers are dry and hot. The arctic tundra or cold deserts are very cold during the year, with bitter and harsh cold winds; the areas are covered with snow and ice. The day has a few hours of sunlight. 2 Vegetation The vegetation mainly consists of small plants, succulents, cacti and so on. The plants include small shrubs, some crop plants, and grasses and so on. The areas are mainly treeless however; some low-growing plants are present like mosses, lichens, grasses and shrubs. Savanna is a mixed grassland ecosystem that has alternating warm and wet climates. The grassland includes the mixed type of vegetation that ranges from the small desert plants to shrubs and some trees in the wet climate. The animals that inhabit are grazing herbivores like gazelles, zebras, giraffe, and elephants. The predators are lions, humans, and hyenas. During the rainy seasons, the different types of grasses and shrubs grow and are able to cope up with seasonal fires. The animals return to their grazing activity as during rains the vegetation is abundant to store food and prevent them from dying in the drought. Elephant serves as the keystone species in the savanna, as these are less in number among other herbivores but their existence influences the climate and the geography of the grasslands...

The way in which three major types of grasslands differ in their climate and vegetation. Explain the way in which savanna animals survive seasonal variations in rainfall. Describe the reason why an elephant is considered as an important component of the African savannah. Provide the reason for the disappearance of many of the world’s temperate grasslands. Describe arctic tundra and define permafrost. Define chaparral and the risks of living there.
