The Okefenokee in Georgia is a typical prairie pothole. A a result, i receives direct precipitation and a considerable amount of runoff from the surrounding uplands as well as ground water inflow. I loses water to evaporation, keping to groundwater or overflow in conditions of excess precipitation and runoff. Wtlands are considered as a complex ecosystem in which underground water and surface water interact with each other, bt since the underground water can’t be observed its function in the cycle of wetlands is difficult to comprehend compared to that surface water.
Wtlands do have the ability to filter nutrients and other constituents, ad this has resulted in the construction of artificial wetlands in other parts of the US Wielder (1989). Hwever, wtland effectiveness in improving the quality of water relies on the hydrologic cycle, tpe of vegetation and the constituent concern Zedler and others, 1985). Te features of wetland soils are because of anaerobic soil bacteria, bth the facultative and obligate bacteria do exist in saturated areas of this kind of grounds. B law, te land is wetland the wetland features are present on or near the surface of the ground.
Wen soils are saturated, ad the air removed from soil pores, aaerobic bacteria become the dominant in the microbic community of the soil. Tese bacteria use the non-oxygen substances as their electron acceptors. Wen organisms respire, tey transfer electrons linearly from one molecule to another. Fom every transfer of electron, eergy is produced for the organism’s life processes. I wetlands, te organisms use a variety of substances as electron acceptors such as nitrate, mnganese, slfate and dioxide.
Snce ferric is quite common in most soils, aaerobic bacterium adds an electron to it resulting in ferrous iron. Sils containing ferrous oxide are white or gray in color while dryer ones are yellow or red. Te presence of a gray soil near the surface of the soil is an indication of a wetland soil. Mnganese, mjorly black in color are also indicators of wetland Cohen (1984). De to inefficiency of anaerobic bacteria in decomposition of matter, te wetland soils tend to be rich in organic matter than soils, te horizon of the soils are entirely composed of organic matter.
Wtland soils filter contaminants in three different ways, ad physical filtration does occur when the...
