What is savanna definition?

A savanna is a type of grassland ecosystem characterized by scattered trees and a relatively open canopy, allowing for a mix of grasses and shrubs to grow. In general, savannas receive enough rainfall to support vegetation growth, but not enough to support a full forest. They are found in tropical and subtropical regions of Africa, Australia, South America, and Asia. Savannas are known for their distinctive wildlife, including large herbivores such as zebras, antelopes, and giraffes, as well as predators such as lions and cheetahs. They are also important grazing and farming areas for humans.
