In essence, the ecosystem definition in biology is that it acts as the fundamental unit of nature. (Ref. Ecosystems confined to small or tiny spaces and yet defined by specific environmental factors are called micro-ecosystems. Similar to biotic components, the abiotic components also have their ecological role. As such, they are referred to as the rainforests of the sea.

In marine biology, the littoral zone includes areas of ocean extending to the ends of the continental shelf, and can be subdivided into three smaller zones based on areas of tidal action. These two processes are linked and essential to the structure, function, and biodiversity of an ecosystem.

Get to know more about these species in this tutorial Freshwater ecosystem is comprised of four major constituents, namely elements and compounds, plants, consumers, and decomposers. Then, they take carbon dioxide and water from their environment to convert them into sugar, a biomolecule that can be used to synthesize chemical energy (such as ATP). Secretara de la Convencin de Ramsar, Gland, Suiza. The littoral zone is the near shore area where sunlight penetrates all the way to the sediment and allows aquatic plants ( macrophytes ) to grow. Gayana Botnica 59: 87-100. Para el concepto de humedal se han elaborado numerosas definiciones, aunque se ha llegado al consenso de que este tipo de ecosistema corresponde a la zona de transicin entre ambientes hmedos y ambientes generalmente secos, presentando caractersticas de ambos, por lo cual no pueden ser clasificados categricamente como acuticos ni terrestres (Barbier et al. For example, a few feet from the shore of a lake, the sediment can be considered to be in both the benthic and littoral zone. What is a simple definition of an ecosystem?

Por otra parte, Comin & Williams (1994) sugieren que los patrones de circulacin del agua, dinmica de nutrientes y las interacciones agua-sedimento son esencialmente similares entre ambientes permanentes y temporales, sin embargo, en estos ltimos, debido a la inestabilidad generada por el secado y llenado de los humedales, estas se encuentran ms estrechamente relacionadas con las condiciones ambientales (e.g., clima, actividad antrpica), y por lo tanto, su susceptibilidad ante perturbaciones de tipo antrpico es mayor.
