Deserts make up close to a fifth of the earth’s surface, and they occur in areas where the annual rainfall is below 50cm. Most of these deserts, such as the Sahara of North Africa, occur at low altitudes though others occur at relatively lower latitudes and are referred to as cold deserts. However, such deserts are more deficient in life...

The figure above shows an example of a food chain found in the desert ecosystem. The food chain is divided into nutritional levels whereby the lowest level is occupied by produces, the second level by primary consumers, the third level by secondary consumers, and the fourth level by tertiary consumers (Feller, 2012). The desert ecosystem is often considered to be...
