Hot deserts are home to a variety of plant and animal life; however, they have a lower level of biodiversity compared to most biomes. The flora and fauna there have successfully adapted to living in a challenging environment. To learn more about biodiversity and adaptation, please click here.

Although hot deserts have low biodiversity, they are functioning biomes with a level of interdependency. Humans use hot deserts for various purposes, including agriculture and mining, and must ensure that the balance of life in the biome is respected and maintained.
