The desert biome is a dry, arid ecosystem characterized by extreme temperatures and very low rainfall, usually about 1 inch per year. Days are hot, nights can be cold. Animals such as camels, lizards, and foxes adapt to conserve moisture and avoid heat. Some plant species native to deserts include succulents, cacti, acacias, creosote bushes, yucca, mesquite, and short grasses.
