Communities of organisms that are dependent on all(prenominal) other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are oceanic ecosystems and fresh water ecosystems. Types Marine ecosystem Marine ecosystems c everyplace approximately 71% of the Earths fold up and contain approximately 97% of the pla meshs water. They generate 32% of the worlds net pri mary production. They are distinguished from freshwater ecosystems by the bearing of dissolve compounds, especially brininesss, in the water. Approximately 85% of the dissolved materials in seawater are sodium and chlorine. brine has an medium salinity of 35 vocalisms per thousand (ppt) of water.

actual salinity varies among opposite oceanic ecosystems. Marine ecosystems can be divided into the side by side(p) 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 force field between high and low tides); estuaries; salt marshes; coral reefs; and hydrothermal ven ts (where chemosynthetic sulphur bacteria f! orm the food base). Classes of organisms make up in shipboard soldier 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: OrderEssay.net
