Introduction: Abovethe two thirds of our planet surface is enveloped with water. The earth’s five oceansand its seas, rivers that comes from rainfall, from snow and ice melting.
not forgetting the lakes and ground water even swamps.They are all connected to present the aquatic area which is a home of hugenumber of living things.The water is very effective and importantmolecule for all organism and it is essential part in life. Most of theorganisms cannot survive without the presence of water. Although, they don’t live inside it such as human andplants and different organisms, they have provided with food from inside it,also passengers and goods are often carried by sea.Thebiodiversity of hydrous ecosystems is one of largest fortunes. When biodiversity word comes on people’s minds, thefirst thing they ever think about is the rainforests.
The rainforests contain ahuge amount of biodiversity, and alot of sorts that we never thought aboutthem. In fact in aquatic oceans there is a similar biodiversity found in there.For instance, coral reefs have been considered as the rainforests of the seabecause they are a home where alot of marine organisms lives in. But coralreefs, like aquatic ecosystems, are easily affected by outside factors.
Abioticfactors are ingredients of a natural environment that are not alive. In otherwords, physical or chemical parts of the environment that affect the organismsthat are in that environment. For aquatic ecosystems, these factors includelight levels, water flow rate, temperature, dissolved oxygen, acidity (pH),salinity and depth.An aquatic ecosystem is a community of living organismssocializing with each other and their surroundings under the water. There are two main kinds of aquaticecosystems called saltwater ecosystem and freshwater ecosystems.Wet lands are areas that are permantly or regularly underfresh or salty water, such as bonds, rivers, bogs, marshes, estuaries andmangrove swamps.While the openocean starts at the edge of continental shelf where the seabed plunges suddenlydown the continental slope to greater depths.
Its divided into three zones: thebenthic zone is at the bottom, above that the demersal zone, and the pelagiczone is uppermost.Ocean currentsare driven by a combination of winds and the earth’s rotation, and they areregulating permanent or continuous movement of ocean’swater. The motion of the ocean water ispromoted by forces acting on the water counting the breaking waves, salinitydifferences, Coriolis effects, the wind and temperaturesWhile oceansurface currents are like large rivers many kilometers wide, on average 100mdeep and flowing at 15 km per hour. also it affect only the top 100m so theocean deep current involve the whole ocean However, the major currents are spilt oneither side of equator into huge rings called gyres.This essay isconcentrating on comparing between fresh and salt water and the features that includeeach ecosystem. we will discuss a few elements that impact aquatic ecosystems.concentrated on the abiotic factors and how they affect aquatic life.
These arethe factors that cause a deep ocean to be totally different from a shallowlake. Plus, it willinclude the types of Ocean currents and their effects in order to work toneutralize the temperature difference between different areas in the oceanssuch the winds do on land. As a body of water warms and cools slowly it’s anexcellent, and fairly stable, transmitter of heat and cold which feeds into theweather system.
