A savanna is grassland filled with shrubs and isolated trees. South America also has savannas, but there are very few species that exist only on this savannah There are over 40 different species of hoofed mammals that live on the savanna. Hoofed mammals are like Giraffe’s, Kobs or Bison’s.
African elephants have its trunks and tusks to keep them alive. An elephant uses its trunk to drink, eat food, and take a bath. It uses tusks to protect itself. They have thin skin, so they don’t get hot that often.
The animals that live in savannas have adapted to a great deal of variability in the food supply throughout the year. They always have plenty of food to keep them alive, but they sometimes have no food or drink (during the dry seasons).
Tropical savannas has plants with dry soil. Plants that commonly grow in tropical savannas have made adaptations that allow them to live long periods of dryness, survive fires and protect themselves from grazing animals. The baobab tree stores water in its trunk and have thick barks which protects them against fire.
In order for the grasses to survive the dry season, they have developed an adaptation that allows them to grow quickly. The Baobab tree has adapted to the savanna biome by only producing leaves during the wet season.
Desertification is the main impact of human activity. The population increases, which lead to more crops to be grown on the land in order to feed people. This leads to over-cultivation, which leads to loss of vegetation and as a result to desertification.
