Transcript of Sahara Desert
The Desert Biome
Egypt, Sudan, Chad, Mali,
Algeria, Niger, Tunisia, and Libya
Range of temp
Average 86 in summer and
Ave. 55 in winter
There are many species of plants and animals in the Sahara Dessert. Some animals include desert eagle owls, desert beetles, camels, spiders, hawks, lizards, scorpions and snakes. Cacti, palm trees and some types of grasses and shrubs are the main plants in the Sahara Dessert. Some of the biotic factors interact through symbiotic relationships. The cactus plant is many herbivores main source of food in the Sahara. The biggest predators in the desert are some types of snakes, owls and lizards. Hawks often prey on lizards and small rodents. Cactus provide food and water lizards, while lizards help the cactus reproduce.
Some areas in the Sahara do not get any rain for a few years at a time
Hours of sun Light
10-12 hours of sunlight depending on your location in the Sahara

How Humans Affect the Sahara
Humans are Over hunting to near extinction
Over use of any water humans find which is putting stress on the area and the ecosystem.
Irrigation with very poor drainage
CO2 levels effect the number of leave on plants
This can be a good thing. It means that some areas could be ready for forestry and agriculture but the water supply might not be able to sustain it.
Long twisted horns and coats change color by season
Rests in shady areas for protection from sandstorms
Prey to lions, cheetahs, leopards, African hunting dogs, and others
Eats grasses and leaves from shrubs, herbs and bushes
Breeding occurs throughout the year but peaks during winter and spring
Life expectancy is 19 years in the wild and 25 years in captivity
Less than 500 are found in the wild
Increase in vegetation means a cooler area
More than 1/4 of the Sahara Desert's surface is sand dunes; some can reach 500 ft
Did You Know?
The Sahara receives enough solar energy in a few hours to power the world for a YEAR
