A savanna is an extensive grassland biome characterized by a mixture of scattered trees and perennial grasses. This type of ecosystem is defined by seasonal climatic variability, typically featuring distinct wet and dry seasons, which dictates the biological cycles of both the flora and fauna. The structure supports a dynamic trophic system, where grasses form the primary producer base, supporting grazing herbivores that in turn sustain various carnivores. Savanna environments are notable for the biomass accumulation in the grasses and the adaptations of the associated life forms to manage periodic cycles of fire and drought, contributing to the maintenance of open woodland structure.
