These plants and animals depend on each other for survival. In a delicate balance, these forms of life help keep each other in a fixed system. If we take an animal or a plant away from an ecosystem, we can have serious problems. As an example, consider what happen when a new plant or animal is introduced into an ecosystem where it didn't exist before. The new organism competes with the natural organisms from that location for available resources. These natural strangers can push other organisms out, causing them to become extinct. This can then affect other organisms that depended on the extinct organism as a source of food.

In the deserts there are few living things.

= FOREST ECOSYSTEMS: =

= = = Temperate forests are moist forests in middle latitude get lots of rainfall mainly because they are in areas of ocean climate.They can be coniferous forests (dominated gymnosperms)or hardwood(predominantly broadleaf plants orangiosperms).They are located northwest of North America,northwestern Europe(Great Britain,Norway and northwestern Spain),southern Chile and Argentina southeastern,southeastern Australia(Tasmania/Victoria)and the west coast of New Zealand).Others,on the contrary grow in subtropical areas east of the Black Sea (northeastern Turkeyand western Georgia),the south and southwest of the Caspian Sea(southeast and northeast of Azerbaijan and northern Iran),the North Island of New Zealand, South Africa,Japan and Taiwan. = = =








 * An automobile, autocar, motor or car is used for Transport. **
 * Most of car are designed to run primarily on roads, to have seating for one to eight people. **
 * Typically have four wheels, and be constructed **
 * for the transport of people. **


 * The history of the automobile begins with the creation of automobiles capable to transpot humans . The first cars powered by fuel gas and the old cars worked with water vapour. **

= = = = =// Why do the British drive on the left side instead of driving on the right ? //=

=== We all know that in the United Kingdom people drive on the left side of the road while in the rest of Europe we do it on the right side. But why do we drive on one or another side of the road? this system of traffic comes inherited from when they were leading carriages. === === In the world the majority of people is skillful, with what the option of the left side seems to be the most logical while you go astride or in carriage thrown by horses. But a good day the car was invented and the thing was a bit complicated. === = video: =

 * Normally, the cars are thrown by horses, mules, donkeys or oxen, though also other animals of shot are used. **

the most important inside parts of a car ar:

**the most important external parts of a car ar:**

=**// THE CAR. //**= **The car, as we know it today, was invented in Germany in 1886 by Carl Benz. Little after other pioneers, such as Gottlieb Daimler and Wilhem Maybach, its models presented at the same time. In 1910, Herry Ford began producting cars on an assembly line, to tally innovative system that allowed him to reach figures of manufacture until then on thinkable.**

=// Parts of the car: //=
 * tire, hood windshield, fender, trunk, seat belt, rearview mirror , steering wheel, brake, gear shift, emergency brake. **

=// WHATS IS THE CAR: //=
 * It is a vehicle with an engine, four wheels, used to move from one place to another. **

= The first motor sport events are linked to the infancy of the automobile, vehicle bypass for being the coach, but the man seems to get along with their needs and aspirations. but the belief that the races are the cause of a particular evolutionary impulse in the art, still embryonic car, does not occur until much later.

 * Though already in 1769 there developed the first vehicle promoted to steam that was weighing 4 ' 5 tons and was reaching 4 Km/h, it was not until 1866 when Gottlieb Daimler invents the first vehicle with engine. Since then up to today there has been numerous advances: internal combustion engine of 4 times, the current car of petrol. **

=**// THE WHEEL: //**=
 * The wheel is a simple machine, and is very important because if not we had the wheel we could travel, nor carry heavy thins... **
 * The wheel is probably the most important mechanical invention of all time. Its origin is to lost time because the people of that time not had neither pen nor paper. Some scientists believe that the wheel was invented in the 5 Millennium. **
 * The first wheels are made of rock, the wheels are were simple discs of rock with a central hole and the wheel don't have round shape. **




 * The next wheel are made of wood and don't have round shape. **






 * The next wheel are made of wood and now have a round shape. **


 * Finally the wheel is made of metal and rubber. Now the wheel is more modern, faster, safer... **
