Desert animals stay dry when it rains. When the rain stops, they come out to drink water.
Rain has the ability to fall in the desert because it is picked up by clouds and transferred. Because the desert has very little to no water available rain must fall for the plants and animals.
Plants provide food and cover for animals living in the desert.
usually, animals in the polar region have thicker coats than animals in desert regions. Also many animals in the polar reagon have white or dull coats to blend into a cold enviorment. Polar: cold region Desert" hot region
The reason that there are less animals in the desert is because the animals that live in the rain forest are used to having more oxygen due to the large amount of trees there. As there are less trees in the desert, there are less animals. This is why most desert trekkers use an oxygen tank.
The rainforest has the greatest biodiversity followed closely by the desert.
Desert plants are important because they provide sources of water for desert animals. Many desert plants, such as cactus, store water inside. They also may provide desert animals with homes, such as how desert owls live inside cactus, and their flowers/leaves often provide food for desert animals, or shade. They are an important part of the ecosystem.
Are you sure you are not referring to a 'rain shadow' desert? I find no reference to a 'rain shower' desert.
so they can provide a habitat for plant and animals.
You can identify it as a Desert if it is, Deserted or some animals and plants live in that certain place. And if only an few Rain in occurs in a Year.
how much rain does the desert get
They get water from the fluids of other animals, eating plants aka/ drinking the moisture on the plants aka cactus, or if there is rain.
