They can be categorized into groups based on where they live (benthic, oceanic, neritic, intertidal), as well as by shared characteristics (vertebrates, invertebrates, plankton). Scientist track these number to manage overfishing so population does not deplete more. This is probably because marine ecology is a relatively new scientific field compared to terrestrial and aquatic ecology. Many marine life have an important role in the world such as the tiny plankton because without them the world would build up with carbon dioxide, the plankton absorbs the carbon dioxide in the air and releases oxygen back into the air. Living organisms within an ecosystem interact in many ways including predation, cooperation, … For example, mussels are the “engineers” of the marine ecosystem [1]. Abelson: Marine ecosystem restoration (MER) is a developing field of applied science and is rapidly growing in importance as marine ecosystem degradation accelerates. Overfishing is a threat for marine ecosystems because a decrease in number of a species will effect the marine food web disrupting the whole ocean. Thus, a more accurate name for Earth would be The aquatic equivalents of biomes are called aquatic life zones. This chain is a way of mutual existence of living beings. As well as the ocean itself we have lagoons, salt marshes, coral reefs and much much more. Marine biodiversity has a numerous variety of species and organism. Marine microbe communities can evolve rapidly in response to environmental shifts and could be used as indicators of ocean change. Marine ecosystem models are valuable tools for understanding marine ecosystem function, structure and productivity under global change. These two marine ecosystems are important because the estuaries are breeding territories for many marine animals, because it is easy for young-lings to survive there, since there are no known predators that live in that region. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. Some important characteristics of the marine ecosystemare: 1.
