Savannas are maintained by drought, fire, and grazing.

Question

Quizplus · Accepted Answer

Savannas are characterized by a seasonal rainfall pattern with long dry periods, which creates drought conditions. Fire helps to maintain the open grassland habitat by controlling the growth of woody plants and promoting the growth of grasses. Grazing by large herbivores also plays a role in shaping the savanna ecosystem by controlling the grasses and promoting a diverse plant community. Without these natural disturbances, the savanna would eventually become dominated by trees and lose its open grassland character.
