arid ecosystems

Arid ecosystems are dry environments characterized by low rainfall, typically less than 250 millimeters (10 inches) annually. These areas include deserts and semi-deserts, where water scarcity limits plant and animal diversity. Vegetation is often sparse, consisting of drought-resistant plants like cacti and shrubs. Despite harsh conditions, many species have adapted to survive with minimal water and extreme temperatures. These ecosystems play vital roles in global climate regulation, support unique wildlife, and influence local water cycles. Their delicate balance can be easily disturbed by human activities, making conservation important.
