A savanna is a unique type of ecosystem characterized by open grasslands with scattered trees. These areas are typically found in regions with a warm climate and seasonal rainfall, which supports a variety of plants and animals. The combination of grass and trees creates a habitat that is home to many species, including large herbivores like zebras and elephants, as well as predators like lions. Savannas play a crucial role in the environment by supporting biodiversity and helping to regulate the climate. They are often found in parts of Africa, Australia, and South America. The balance between grass and trees in savannas is maintained by factors such as fire and grazing, which prevent the area from turning into a dense forest.
