1. Eutrophication
   Eutrophication (Greek: eutrophia—healthy, adequate nutrition, development; Eutrophie) or more precisely hypertrophication, is the ecosystem response to the addition of artificial or natural substances, such as nitrates and phosphates, through fertilizers or sewage, to an aquatic system. One examp...

3. Eutrophication
   Usually, the limiting factor on how many living organisms can grow in a body of water is the supply of nutrient elements such as nitrogen and phosphorus. If these are supplied in overabundance (for example, by pouring fertilizer into the lake), plants and bacteria can multiply to such an extent that...

4. Eutrophication
   The slow aging process during which a lake, estuary, or bay evolves into a bog or marsh and eventually disappears. During the later stages of eutrophication the water body is choked by abundant plant life due to higher levels of nutritive compounds such as nitrogen and phosphorus. Human activities can accelerate the process.

5. Eutrophication
   Aquatic plant growth is stimulated to produce excessive choking growth. The process involves a complex series of inter-related changes in the chemical and biological status of a water body most often due to a depletion of the oxygen content caused by decay of organic matter resulting from a high level of primary productivity and typically caused by enhanced nutrient input.

9. Eutrophication
   Eutrophication is a process taking place in natural waters. The process is characterized by development of an environment rich in nutrients and consequent proliferous plant production.

10. Eutrophication
    is the enrichment of aquatic environments with high levels of dissolved plant nutrients, such as nitrate and phosphate ions, leading to high algal growth. It is a natural process that can be exacerbated by human activity e.g. from leached fertilisers
