The Desert By: Daniel, Vikram, and Austin
2
Geographic Location 30 degrees north and 30 degrees south
Found in North America, Arabian peninsula, Australia and small parts in North America Largest Desert in the world is the Sahara desert located in North Africa
3
Climate - Temperature range The mean temperature range is from degrees celsius the extreme maximum range is from degrees celsius Precipitation totals Deserts receive less than 25 centimeters a year of precipitation. The months from December to March receive the most rainfall
4
Soil Very Dry Clump Vegetation
Most desert soils are called Aridisols (dry soil)
5
Native Plants Adaptations to biome
desert plants have adapted to the extremes of heat and aridity by using both physical and behavioral mechanisms, The cactus Dominant vegetation Plants are almost all ground-hugging shrubs and short woody trees. Cactus Tumbleweed Wildflower
6
Native Animals 1st Order Consumers Cactus and Sage bushes
2nd Order Consumers Butterflies and Chuckwalla 3rd Order consumers Snakes and Lizards 4th order consumers Roadrunner Decomposer Beetle Scavenger Crow
7
Keystone Species Humming Bird
Pollinates many varieties of native cactus and other plants If it was removed All the cacti will die which would cause all the producers to die which would cause all the animals that eat the producers to die
8
Indicator Species Prickly Pear Cactus and Sagebrush
Very abundant in low elevations and in arid basins as well as in dry grasslands
9
Endangered Species Antelopes Over-hunting Gazelles Over-hunting
10
Invasive Species Buffel grass
It is invasive because it is not native to the area it inhabits and it takes up all the resources that are necessary for the other species to survive Grows densely and crowds out native plants Dense roots and ground shading prevent germination of seeds
11
Food Chain
12
Services Provided Services done by native plants included sources of food, medicine, and energy The plant diversity in this ecosystem provided economic service benefits, such as sources of fodder, fuel-wood, and traditional medicinal plants
13
Human Impact Off-Roading
Carve Tracks in the Soil that scar the earth for years Cause plants and animals to die The drilling of fossil fuels Kills vegetation and wildlife Disrupts the ecosystem
14
2 Interesting Facts Deserts take up about ⅓ of the earth's land surface The first dinosaur eggs discovered were found in the Gobi desert in 1923
