What is the defining characteristic of a desert biome?

The primary characteristic is low precipitation, typically less than 250 mm annually, which leads to high evaporation rates.

Xerophytes are plants that have evolved specifically to survive in environments with very little liquid water, such as cacti.

How do desert animals avoid heat?

Many desert animals use nocturnal behavior, burrowing underground, or have physiological adaptations like concentrated urine to conserve water.
