What Are the Biotic and Abiotic Factors of Desert Biomes?

The biotic factors of the desert biome include the living organisms, such as plants and animals, that call the desert home, while abiotic factors include the elements and resources to support life, such as sunlight, water and air. Deserts around the world vary in the number and variety of living organisms that they support; their ability or inability to support life depends largely on the availability of abiotic factors.
