Explanation- Savanna are tropical grasslands that are located near the equator, between the Tropic of Cancer and the Tropic of Capricorn. They cover much of Africa as well as large areas of Australia, South America, and India. They may have some drought-resistant, fire-resistant or they may have an open shrub layer. Savanna is characterized by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Savanna is also known as a paradise of the hunters.
