A savanna is a type of grassland ecosystem characterized by a mix of open grass areas and scattered trees. It typically experiences a warm climate with distinct wet and dry seasons. Savannas are found in regions such as Africa, Australia, and parts of South America. They support a variety of wildlife, including large herbivores like zebras and elephants, as well as predators like lions. The vegetation in savannas is adapted to withstand periods of drought and fire. Grasses dominate the landscape, while trees are often spaced apart to allow sunlight to reach the ground. This unique environment plays a crucial role in maintaining biodiversity and supporting various animal species.
