desert, any large, extremely dry area of land with sparse vegetation. It is one of Earth’s major types of ecosystems, supporting a community of distinctive plants and animals specially adapted to the harsh environment.
What are desert ecosystems called?
Deserts are extremely dry environments that are home to well-adapted plants and animals. The main types of deserts include hot and dry deserts, semi-arid deserts, coastal deserts, and cold deserts.
Is tropical desert an ecosystem?

Rainfall is sporadic and in some years no measurable precipitation falls at all.
What makes an ecosystem a desert?
In general, deserts are made up of a number of abiotic components – including sand, the lack of moisture, and hot temperatures – basically anything that makes up an ecosystem that isn’t alive.
What is the desert habitat?
What are desert habitats? Deserts are places that don’t get much rain, and are very dry. They can be either hot places, or cold places. Because deserts don’t have much water, animals that live in the desert are able to conserve water and keep their body temperature at the right level.
Where is the desert ecosystem located?
Hot and dry deserts can be found in North America, Central America, South America, southern Asia, Africa, and Australia. Well-known hot and dry deserts include the Mojave and the Sahara.
What is a desert in geography?

Why are deserts fragile ecosystems?
Wide temperature fluctuations have another effect. Warm air rises, and cool air sinks; rapid temperature change causes desert air to move rapidly from place to place. … Because they impose such harsh extremes of heat and aridity, deserts are among the most fragile ecosystems on the planet.
How many plants live in the desert?
There are at least 2,450 native plant species found in California’s desert, according to a great article by Chris Clarke on desert life, posted at KCET.
