The predominant vegetation found in deserts is typically scrub and cacti, which have adapted to survive in arid conditions. Vegetation in deserts is characterized by low moisture levels with scant rainfall, leading to the growth of hardy plants that require minimal water. These plants have adapted through various mechanisms, such as deep root systems and water retention strategies. Other common desert plants include succulents and tough, drought-resistant species. The distinct vegetation plays a vital role in the desert ecosystem, providing shelter and food for various wildlife.
