The main characteristics of a desert ecosystem include low precipitation, high temperatures, and limited vegetation. Deserts typically have sparse vegetation due to their arid climate, with most species adapted for surviving in dry conditions. Vegetation is often dominated by xeric shrubs, such as cacti and mesquite trees, which can store water in their stems and leaves. Desert soils tend to be shallow and rocky, making it difficult for plants to take root. In addition, windblown sand and dust create an inhospitable environment for many living things.
