each of the question from 16 to25.

Since water is the basis of life, composing the greater part of the tissues of all living things, the crucial problem of

desert animals is to survive in a world where sources of flowing water are rare. And since man s inexorable necessity is to absorb

’

large quantities of water at frequent intervals, he can scarcely comprehend that many creatures of the desert pass their entire

lives without a single drop

Uncompromising as it is, the desert has not eliminated life but only those forms unable to withstand its desiccating effects. No

moist- skinned, water loving animals can exist there. Few large animals are found: the giants of the North America desert are

–

the deer, the coyote, and the bobcat. Since desert country is open, it holds more swift footed, running, and leaping creatures

–

than the tangled forest. Its population are largely nocturnal, silent, filled with reticence, and ruled by stealth. Yet they are not

emaciated. Having adapted to their austere environment, they are as healthy as animals anywhere in the world.

The secret of their adjustment lies in a combination of behavior and physiology. None could survive if, like mad dogs and

Englishmen, they went out in the midday sun; many would die in a matter of minutes. So most of them pass the burning hours

asleep in cool, humid burrows underneath the ground, emerging to hunt only by night. The surface of the sun baked desert

averages around 150 degrees, but 18 inches down the temperature is only 60 degrees.
