The Savanna or Savannah
The Savanna is a biome that is typically found in Africa and is characterized by a tree density low enough to allow sunlight to reach the ground and allow for smaller plants such as grasses to grow. The growth of these grasses provides an optimal food source for herbivores, which is why large grazing herbivores such as zebras are found here. The presence of these herbivores allows for the existence of larger carnivores such as lions.
