An ecosystem is a combination of all the biological and physical properties of the natural world, usually in a recognizable area. If that definition sounds rather dauntingly academic, its for two reasons: First it is academic definition , and second, the term “ecosystem” is not easy to define satisfactory.

For this reason, enormous aquatic reptile fossils are found in places like Nebraska. In general,such changes occurs slowly,or at least at a rate most humans would consider slow. It took well over a hundred million years for Kansas to change from a vast sea of salt water populated by swimming monsters to a vast sea of grass populated by walking and running monsters. “The concept of the ecosystem is a highly instructional tool with which humans may easily learn a great deal about their planet and significantly enrich their trips to museum and zoos”. The concept is useful in this regards because it allows us to organized an enormous amount of information into manageable chunks. Much of this consists of information a well informed person already knows but simply hasn't thought about in an organized,ecological way. The African continent ,however ,has many ecosystem for example,the Sahara ,the East African Savannah, the steamy forests of the Congo River basin. Each tend to be characterized by its own mixture of temperature and moisture,as well as its own insisting of the species that lives in those ecosystem and feed on one another. The ten minute ecologist needs to be aware of two truly important concepts that apply to ecosystem. One of these concepts is that of flows the other one is that cycle. Perhaps the best...
