After such organisms die, the bacterial degradation of their biomass consumes the oxygen in the water, thereby creating the state of hypoxia. According to Ullmann's Encyclopedia, "the primary limiting factor for eutrophication is phosphate. Phosphorus is a necessary nutrient for plants to live, and is the limiting factor for plant growth in many freshwater ecosystems.

Phosphate adheres tightly to soil, so it is mainly transported by erosion. Once translocated to lakes, the extraction of phosphate into water is slow, hence the difficulty of reversing the effects of eutrophication. Excess nutrients are applied to the soil.

Some nutrients leach into the soil where they can remain for years. Eventually, they get drained into the water body. Some nutrients run off over the ground into the body of water. The excess nutrients cause an algal bloom. The algal bloom blocks the light of the sun from reaching the bottom of the water body.

The plants beneath the algal bloom die because they cannot get sunlight to photosynthesize. Eventually, the algal bloom dies and sinks to the bottom of the lake. Bacteria begins to decompose the remains, using up oxygen for respiration.

The decomposition causes the water to become depleted of oxygen. Larger life forms, such as fish, suffocate to death. This body of water can no longer support life. Cultural eutrophication Cultural eutrophication is the process that speeds up natural eutrophication because of human activity.

Extra nutrients are also supplied by treatment plants, golf courses, fertilizers, farms including fish farmsas well as untreated sewage in many countries. This decomposition process consumes oxygen, which reduces the concentration of dissolved oxygen.

The depleted oxygen levels in turn may lead to fish kills and a range of other effects reducing biodiversity.

Nutrients may become concentrated in an anoxic zone and may only be made available again during autumn turn-over or in conditions of turbulent flow. Enhanced growth of aquatic vegetation or phytoplankton and algal blooms disrupts normal functioning of the ecosystem, causing a variety of problems such as a lack of oxygen needed for fish and shellfish to survive.

The water becomes cloudy, typically coloured a shade of green, yellow, brown, or red. Eutrophication also decreases the value of rivers, lakes and aesthetic enjoyment. Health problems can occur where eutrophic conditions interfere with drinking water treatment.

Runoff from agriculture and development, pollution from septic systems and sewerssewage sludge spreading, and other human-related activities increase the flow of both inorganic nutrients and organic substances into ecosystems.Week 6 assignment IT/ FEB/2/ Brbara Hecker Week 6 assignment In order to understand how to configure a router and switch we must start form the bottom to the top.
