The document discusses key aspects of desert ecosystems. It notes that deserts have a very dry and warm climate with little rainfall, and some can exceed 100 degrees Fahrenheit. Deserts are typically located within 30 degrees of latitude and include locations in mountains and California's Mojave Desert. The animals that live in deserts, such as camels, lizards, rattlesnakes, and kangaroo rats, have adapted to survive the hot weather conditions. Desert plants like cacti, saguaro, and creosote bushes are also adapted to the hot, dry climate and do not require much water.
