Hi fellow members

Please go through this short passage and correct it for me. Many thanks in advance.

A desert is a very dry place. Animals that live there cannot always find water. However, many small desert animals do not have to drink any water.. They get water they need by eating desert plants which have water stored in them.
During the day, most desert animals stay underground or in the shade. The hot sun would make them sweat and they would lose much of the water in their bodies. To overcomes this problem, these animals come out at night when the desert is cool and so they do not sweat.
The camel must drink water. But once it has drunk, it can go on for days without drinking any more. Its body can store a lot of water. It can stay out in the hot sun because it sweats very little and therefore it hardly loses any of the water in its body.
