Desert ecosystems are found in regions that receive very little rainfall. They are characterized by extreme temperatures, ranging from scorching hot during the day to freezing cold at night. Despite these harsh conditions, deserts are home to a variety of plants and animals that have evolved unique adaptations to survive.

Plants in the desert, such as cacti and succulents, have thick waxy skins or spines to reduce water loss through evaporation. They also store water in their stems or roots to sustain themselves during periods of drought. Animals have also developed special features to cope with the desert environment. For instance, camels have humps that store fat, which can be metabolized into water and energy when food and water are scarce.

Desert habitats also support a diverse range of insects, reptiles, birds, and mammals that have evolved efficient ways to obtain water and regulate their body temperature. They often have adaptations like nocturnal activity patterns, specialized digging or burrowing abilities, and the ability to withstand long periods without water.
