Biomas terrestres: la sabana

Savannahs, or tropical grasslands, are located near the Equator in South America, Central Africa, and northern Australia, covering 20% of Earth's surface. They experience two main seasons: a dry winter and a humid summer. High temperatures and irregular rainfall limit tree growth but support grasses. Fires, though destructive, are crucial for nutrient cycling. Savannah plants have adapted with deep roots, fire-resistant bark, and thorns. The region hosts large herds, like the Serengeti wildebeest, which migrate for pasture. The balance of destruction and creation makes savannahs fascinating ecosystems.
