What is the biome that supports very little life due to lack of water?

A biome can be defined as a major ecosystem that is spread over a significantly large geographical area and is characterized by specific plant and animal life. Each biome can be thought of as a distinct system that has characteristic life forms (both plant and animal). The plants and animal species characteristic of a biome are a function of the climate.
Some examples of the biomes are arctic region (or polar), tundra, boreal forests, prairie, temperate deciduous forests, savanna, tropical rainforests, desert, and so on.
Among these biomes, a desert is characterized by the presence of very little water. Deserts are characterized by low precipitation (less than 250 mm a year) and high evapotranspiration levels (more than 250 mm a year). These are regions that are extremely hot during the daytime and in some areas are very cold at night. Plant life is very sparse and typically drought-resistant. These plants are characterized by spines, tiny leaves, and photosynthetic bark. Reptiles and ground-dwelling rodents are the typical animals present in this biome. Some examples of the animals dwelling in the desert include snakes, lizards, jackrabbits, desert foxes, and burros.
Hope this helps.
