What are the biotic factors of the savanna grassland biome?

Savannas are dominated by grasses and have a sparse tree population. Savannas are home to large grazing animals and their predators. In Africa, this includes the zebra, buffalo, antelope, lions, cheetahs, and other large cats. In Australia, the large grazer is the kangaroo and one of its only predators is the dingo. Other biotic factors of the savanna biome are the large insect populations, especially ants and termites, and small burrowing mammals. These include mice, moles, gophers, and ground squirrels.
