Desert Biome


- The desert biome is very hot and dry. Light winds often occur which evaporates any type of moisture.

- Found in lower latitudes between the Tropic of Cancer and the Tropic of Capricorn (ex. The Sahara desert in Africa).

Abiotic Factors

Soils are coarse-textured and sandy, and this combined with high temperatures and little rainfall makes it hard for many types of plants to grow.

Biotic Factors

- In order for plants to survive in a desert biome they must be able to store and collect water, and keep it from evaporating. The plants in this area include: Cactus, shrubs, Cardón, Camel Thorn Tree, Prickly pear, and Saguaro.

- The majority of the animals in the desert are nocturnal and get their water from their source of food. The animals in this area include: Snakes, lizards, Dingo, Coyote, Porcupines, rabbits, etc.

- Plant adaptations: The cactus has a hairy texture that helps reflect the heat from the sun and the aloe plant has a waxy surface to help retain water.

- Animal adaptations: Camels have humps that store fat (not water) that they can metabolize for energy. The Fennec Fox has kidneys which have adapted to restrict water loss.


Importance of Biome

The desert biome is important because it is the habitat of the many animals that live in its ecosystem. The desert is also a source of sand and in many places, oil.

Human Impacts on Biome

Humans have impacted the desert biome by...

- Polluting the atmosphere, which affects the deserts temperature through global warming.

- Drilling for fossil fuels, which causes pollution and harms the animals.

- Taking sand and overhunting animals in the desert, which causes animals to become endangered or go extinct.
