Overview

In this section, include a brief description of the allocated ecosystem. You should include the following information:

Location of the ecosystem

Sahara Desert

Description of ecosystem : The Sahara is the world's hottest desert , the third largest after Antartica and the Arctic . At over 9,400,000 square kilometres (3,600,000 sq mil ) , it covers most of North Africa , making it almost large as China or the United States . The Sahara streches from the Red Sea , including parts of the Mediterranean coasts to , to the outsskirts of the Atlantic Ocean . To the south , it is delimited by the Sahel , a belt of semi-aris tropical savanna that composes the northern region of central and western Sub-Saharan Africa .

Biodiversity of ecosystem (richness of life in ecosystem)

The Sahara Desert is the largest hot desert in the world and occupies approximately ten percent of the African continent . Although species richness and endemism are low , some highly adapted species do survive with notable adaptations . In vast portion of Sahara merely rock , sand and sparse vegetation are found . The remnant large mammal fauna is highly threatened by ongoing over-hunting . An alternative name of Sahara is the Great Desert

Physical Factors

Search the Internet for information on the following physical factors in the allocated ecosystem.

Light (availability of sunlight in the ecosystem),

Not many light intensities in the desert with strange colours of sunset , such as orange and reds and pinker shades .

Temperature (temperature of the ecosystem),

The Chart Of The Weather In Each Month

The Sahara Desert is one of the hottest regions of the world , with a mean temperature over 30C . Daily may also be extreme : a swing from 37.5 to -0.5C has been observed

Water (water quality in the ecosystem),

Sahara Desert very little rain , but there is a lot of water under the desert . Rain that fell thousands of years ago stays underground in pools called aquifers . There are about 4 billion gallons of water under the Sahara Desert . People drill wells more than 1000 feet deep to get it .

Air (quality of air in the ecosystem),

The is global warming is effecting the desert because it is now two times hotter , so by polluting the air the desert will be hotter and hotter in time being .

Classification of Living Organisms

Classify at least eight of the living organisms found in the allocated ecosystem into the categories below:

Producers
Primary Consumers
Secondary Consumers
Tertiary Consumers
Decomposers

For each of the living organism, find a picture and write a short description on the organism. You may wish to include feeding habits, region in the ecosystem where it is normally found etc.

Food Web

Create a food web using at least eight of the living organisms listed above. You may wish to use Microsoft PowerPoint to create your food web. Save your food web as a picture. Finally copy and paste your picture in this section of your wiki.
