Description

Desert Biomes are hot and dry and seldomly recieves rainfall.The Desert biome is unique because it have very few plants or animals and is mostly sand. Desert biomes takes up 1/5 of the Earth's land surface.

Abiotic Factors

The temperature range for a Desert Biome is 55° F to 75.2° F in the summer and in the winter the temperatures go to 41° F or below. The average temperature is 92.6°F The average precipitation for a Hot and Dry desert biome is . For a Semiarid it is 2-4 cm annually. In Coastal Deserts the average rainfall measures 8-13 cm anually.

Animals

An animal that is well adapted to life in the desert is the camel because the humps on their back because they can store water in them. They're eyelashs are long to keep sand out of their eyes and their toes are spread out to keep them from sinking into the sand. The Honeypot Ant is also well adapted because they are able to store fluid in their abdomen. The Armadillo is adapted to living in the desert because it has a hard shell to protecting it from predators. Another animal that has adapted is the Scorpion because they have a poisinous stinger at the end of their tail.

Plants

Very few plants are adapted to living in the desert. Cacti are one of them because its anatomical and physiological features help it to conserve water. The Mosquite tree has adapted by growing roots that extended into the ground up to 30m to get water. The Saguaro has adapted by slowing its growth process ( up to 80 years to reach 6m) to conserve energy. The Desert Sand Verbena grow quickly and spread alot of seeds before dying.

Food Chain

Snakes => Scorpion => Honeypot Ant => Desert Sand Verbena


Human Impact


People who do off road driving impact the biome negatively because they unearth plants, which affects the animals that eat those plants.
