Answer:
The correct answer is savanna. Savanna is the biome which is mainly covered with very tall grasses and scattered trees and shrubs. Except for antartica it is present in all the continents of the world and covers over 20% of the earth's surface.
Savanna covers nearly half of Africa and is the home of many wild animals like lions, cheetah, leopard, hyenas, deer species, wild buffalo, antelopes, etc. There are two seasons in savanna dry season and wet season.
Dry season comes with the winter and is a very difficult season for animals and plants because of the scarcity of water, the wet season comes when summer comes and in this season lots of rain occurs which supports the rich wildlife of savanna and growth of grasslands.
