| Abstract | ||
| Ecosystems are functional units of permanent life on earth. They compose of biotic and abiotic materials. They are in a continuous active prospect of sustainability, characterized by the continuous production of organic materials. Ecosystems were found since thousands of years. Inspite of their differences they share two major characters:-They depend on infinite non polluted source of energy, the sun. Secondly they have efficient ability to recycle the nutrients, during many different chemical and biological activities. So the wastes did not accumulated in the ecosystems and the major elements of primary productivity return back to the plant. The diversity of biomes was due to the differences of their environmental factors. The Aquatic Biome is the largest one .it comprises of Marine Biome 97.5% of water and Freshwater Biome 2.5% ( including 1.7% glaciers and ice in the poles, and 077% of freshwaters in rivers , lakes and ,marshes). So the new conflict in the world is about controlling this vital source of freshwater, because of the rapid increase of human population, high demand on freshwater and the decrease of freshwater quantity together with the increasing water pollution, climate changes and global warming. | ||
