 * 1.Print a map  to copy and paste a map into the Paint Program on your computer. Color in the areas to show where a person can find your ecosystem. Label the major bodies of water and countries it might border. **

The Sahara's topographical features include shallow basins, large oasis depressions, serirs or regs, plateaus, mountains, sand sheets, dunes and sand seas. The highest part of the desert is at the summit of Mount Koussi, which is 11,204 feet (3,415 m) high. However, the lowest point of the Sahara is 436 feet (133 m) below sea level: in the Qattera Depression in Egypt. Over 25 percent of the Sahara's surface is covered by sand sheets and dunes. The most common types of dunes include tied dunes, blowout dunes, barchan and transverse dunes, longitudinal seirfs, and complex sand seas. Within the Sahara are several pyramidal dunes that reach over 500 feet in height while the draa, a mountainous sand ridge, reaches over 1,000 feet. Researchers have for many years tried to figure out how these dunes were formed, but the case remains unsolved.**3. Collect (5) five images or photos that describe your ecosystem. Copy and Paste them into a Word Document.** 4. Describe a serious problem that you have discovered about your ecosystem, and how you could solve it? Pollution is causing the desert problems, along with heat lack of water drought. Also over farming can put pressure on the land and animals in the desert.
 * 2. Describe (3) three physical features of your ecosystem.**


 * 5 - 8. Mark below what seasons your ecosystem experiences, and a brief description of what the physical features (landscape) might look like. **



Meteorologist**s **The climate in the desert is very odd. The desert is very hot and dry. It gets very little rain. Some ===1 - 4. An ecosystem is characterized by its seasons (Winter, Spring, Summer, and Fall) Describe the weather conditions and the type of seasons this ecosystem experiences. Give high and low temperature ranges and note rain and snow precipitation. (Note: Your ecosystem may not have every season.) ===

===6. As an scientist, why do you think it is important to research the weather of an ecosystem? Be able to support your opinion with facts. ===

It is important because you have to be exact on the weather and to be right you research the weather.
 Botanist: The desert's soil is in the day time hot and dry, in the night it's cool and soft. The Joshua tree is 15 to 40 feet high and has a diameter of 1 to 3 feet. It got it's name from Morman pioneers which reminded them of Joshua from the bible in the Old Testement. The desert iron wood is at least 15 to 25 feet, but it grows to be 30 feet tall.There the tallest tree in the Sonoran Desert. The jumping cholla is 10 inches which is 25 centermeters tall.The jumping cholla looks cutely from a far distance, but it has painful spikes that can hurt you when you get too close. The jumping cholla has several abilitys to survive the desert. It has thick coverings of shade spines to give itself shade and protection from the sun, and the spines protecets itself from getting eaten. The desert ironwood grows very slow, but can live for 1,500 years. The jumpimg cholla lives from April to may. The Joshua tree can live for 200 years it belongs to the lily family. Some of the producers are the Mojave Aster, Ocotillo and Triangle-leaf Bursage. The Deconposers are the earth worms and dung beetles. All the plants I said were producers are near the bottom of the food chain. So are the deconposers. Dung beetles are another type of beetles that are invertebrates, and eat dung they keep flies from breeding through it and give the soil nutrients. A earth worm has five hearts,that's like five lives! There many ways for a plant to survive the hot desert. For example the brittle bush has leaves that protect it from the heat and cold, and give moisture in the plant through air. The crimson hedghog cactus must face the heatness of the desert, the cold nights, and other animals eating it.

The sun determines how fast or slow the decompostion works. Zoologist  its physcial <span style="color: rgb(0,0,0);">

<span style="color: rgb(255,255,255);"> <span style="color: rgb(0,0,0);">Pick (1) one animal from your ecosystem and describe its physcial features/characteristics and how it has adapted to the seasonal changes. Armdillo lizard; It is active in daytime. Armidillo lizard borns in summer time and there only one or two baby each time. This animal eat inscets. Armdillo lizard isn't endangerd animal.** Over population coulf brake food chain fo example if there's too much snake the food of snake will decrease alot and other animal that eats same thing as snake animal will starve and die. <span style="color: rgb(0,0,0);"> Give an example of competition between animals. What impact does this have on survival? Scorpion: If Theres plenty of food they wont fight but if there is not eneough food or place to survive they start to fight and fight until they decide who is more stronger or until somebody dies. 4 - 8. List (5) five animals that live in your ecosystem. Describe at least (1) one characteristic about each, that helps them adapt to their environment. Kangaroo rat, scorpion,rattle snake, lizard, fox. Kangroo Rat: Kangroo rat lives in deep burrow. This animal eats seeds, leaves, stems, buds, some fruit, and insects. This animal has very long legs. It is very active when its 5c' decrease.**
