What are examples of biotic and abiotic factors in a desert biome?

There are several biotic (living) and abiotic (nonliving) factors that are common to all types of desert biomes, or ecosystems, including cacti, fire ants, high daytime temperatures and sand. Biotic factors also include plants and animals such as sagebrush, scorpions, lizards and snakes. Abiotic factors include low temperatures at night, wind, and lack of rainfall.

About one-third of the land on earth can be classified as an arid or semi-arid desert area. Although inhospitable, humans have tried to live in deserts for many thousands of years. The most successful have been nomads, who keep moving to wherever food and water are available.
