Why savanna and grassland plants survive drought heat fires?

Savanna and grassland plants have evolved several adaptations that enable them to survive drought, heat, and fires. Their deep root systems allow them to access moisture from deeper soil layers, while their ability to grow rapidly after fire helps them recover quickly. Additionally, many of these plants possess thick, waxy leaves or are drought-deciduous, reducing water loss during dry periods. These traits collectively facilitate their resilience in harsh conditions.
