What is a desert biom?

technically qualifies as a desert as a desert. The desert biom mostly lies in subtropical latitudes, stretching through parts of Asia, Africa and North America. To survive here, Flora and Fauna must compete for water and resist hard sunlight, high temperatures and strong winds.

Desert biom can be divided into dry, cold, shrub and coastal desert. In general, Sandy, rocky soil rich in mineral nutrients, but poor in organic matter. Temperatures vary highly, especially for high altitude deserts, from 111 ° F (44 ° C) to freezing 0 ° F (-18 ° C). The deserts are often formed in the shadow of large mountain belts that block storms and bring winds that carry too much moisture. In fact, more humidity evaporates into the atmosphere than in most deserts. Plants remain a spread out to access sufficient moisture in the ground. These drought -resistant plants are known as xerophytes. Some of them have adjusted the deomat, pores that may duringStorms open and absorb water, but close during the heat of the day. Unlike most of the world, the leaves do not have to compete for sunlight, but to protect themselves from its burning force.

With such a small cover of plants, erosion is a serious problem. Some areas with dunes will move a considerable amount of soil in a process called deflation. Strong wind moves light grains of sand to form and reform dunes. There, almost no plants or animal can live on a constantly changing surface.

In more hospitable areas, night animals take advantage of the cold dawn, dusk and night. Kangaroo rats, owls, snakes and bobcats are all hunting or forage under covering darkness. During daylight they throw deep below the ground or remain in the shade of cacti. There are a rich number of different reptiles, amphibians, insects, birds and rodents in the deserts of coastal or shrubs.
