Mahadev Walmik Shewale is a student in Class S Y B.com, Division A with Roll Number 131525. His project is about desert ecosystems. Deserts are classified based on their average annual moisture deficit. They feature mountain and basin deserts, hamada deserts consisting of plateaus, regs made of rock pavements, and ergs formed by sand seas. Desert flora includes shrubs, cacti, and bushes that have adapted to the dry conditions. Desert fauna, like kangaroo rats and coyotes, remain hidden during the day to conserve energy and moisture. Water sources can also be dangerous due to flash floods.

- 3. 1.1 Classification Deserts are part of a wide classification of regions that, on an average annual basis, have a moisture deficit (for example, they lose more moisture than they receive)
- 4. 2 Desert features Mountain and basin deserts Hamada deserts, which consist of plateau landforms Regs, which consist of rock pavements Ergs, which are formed by sand seas Intermontane Basins
- 5. 2.1 Flora Deserts have a reputation for supporting very little life, but in reality deserts often have high biodiversity. Some desert flora include shrubs, Prickly Pears,Desert Holly, and the Brittlebush
- 6. Fauna Desert fauna include animals that remain hidden during daylight hours to control body temperature or to limit moisture needs. Some fauna includes the kangaroo rat, coyote, jack rabbit, and many lizards

Editor's Notes
- #7: Desert fauna include animals that remain hidden during daylight hours to control body temperature or to limit moisture needs. Some fauna includes the kangaroo rat, coyote, jack rabbit, and many lizards. These animals adapted to live in deserts are called xerocoles. Many desert animals (and plants) show especially clear evolutionary adaptations for water conservation or heat tolerance, and so are often studied in comparative physiology, ecophysiology, and evolutionary physiology. One well-studied example is the specializations of mammalian kidneys shown by desert-inhabiting species.[12] Many examples of convergent evolution have been identified in desert organisms, including between cacti and Euphorbia, kangaroo rats and jerboas, Phrynosoma and Moloch lizards. The sand cat is one of the animals that inhabits certain deserts.
- #8: Atacama is the driest place on Earth and is virtually sterile because it is blocked from moisture on both sides by the Andes mountains and by the Chilean Coast Range. The cold Humboldt Current and the anticyclone of the Pacific are essential to keep the dry climate of the Atacama. The average rainfall in the Chilean region of Antofagasta is just 1 mm per year. Some weather stations in the Atacama have never received rain. Evidence suggests that the Atacama may not have had any significant rainfall from 1570 to 1971. It is so arid that mountains that reach as high as 6,885 meters (22,590 feet) are completely free of glaciers and, in the southern part from 25°S to 27°S, may have been glacier-free throughout the Quaternary, though permafrost extends down to an altitude of 4,400 meters and is continuous above 5,600 meters.
