Introduction
An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are oceanic ecosystems and freshwater ecosystems.

Types
Marine ecosystem
Marine ecosystems cover approximately 71% of the Earths surface and contain approximately 97% of the planets water. They generate 32% of the worlds net primary production. They are distinguished from freshwater ecosystems by the presence of dissolved compounds, especially brininesss, in the water. Approximately 85% of the dissolved materials in seawater are sodium and chlorine. brine has an average salinity of 35 vocalisms per thousand (ppt) of water.



actual salinity varies among different marine ecosystems.
Marine ecosystems can be divided into the following zones: oceanic (the relatively shallow part of the ocean that lies over the continental shelf); profundal (bottom or deep water); benthal (bottom substrates); intertidal (the area between high and low tides); estuaries; salt marshes; coral reefs; and hydrothermal vents (where chemosynthetic sulfur bacteria form the food base).
Classes of organisms make up in marine ecosystems include brown algae, dinoflagellates, corals, cephalopods, echinoderms, and sharks. Fish caught in marine ecosystems are the biggest source of commercial foods obtained from wild populations
environmental problems concerning marine ecosystems include...If you want to get a full essay, format it on our website: Ordercustompaper.com
