A camel can do without water for days together because they sweat very little. Camels can stand high body temperature. They don’t need to sweat and therefore can retain the water they drink
for long periods of time.
The smaller animals fulfill their need for water by burrowing underground during the hot day and come out at night to eat. Some of them eat other animals and get the water they need from the moisture in the meat. Others eat plants and seeds and get the water they need from plant juices.
In a desert the temperature rises during the day and falls rapidly at night because of the absence of moisture in desert lands. The moisture present in the air acts as a blanket and protects the earth’s surface form the hot rays of the sun but the moisture in air is absent in desert.Therefore, the land get heats up quickly during the day due to the sun’s rays and cools down rapidly at night.
