Cacti are predominantly found in a desert climate. This type of climate is characterized by low precipitation and high temperatures, creating arid conditions suitable for cacti to thrive. These plants have adapted to conserve water through their thick, fleshy stems and spines that deter herbivores. Cacti are primarily found in regions such as the Sonoran Desert and other warm, dry areas around the world. Their unique adaptations allow them to survive in harsh environments, making them a significant part of the desert biome and valuable for ecological diversity.
