eutrophication – מילון אנגלי-אנגלי
eutrophication
n.
slow aging process during which a lake or other body of water evolves into a marsh or bog and eventually disappears, process by which a body of water becomes enriched in nutrients that stimulate the growth of aquatic plant life and eventually disappears; (Agriculture) process of becoming eutrophic
Eutrophication
Eutrophication (
Greek:
eutrophia (from
eu "well" +
trephein "nourish".); ) or more precisely
hypertrophication, is the ecosystem's response to the addition of artificial or natural nutrients, mainly
phosphates, through
detergents,
fertilizers, or
sewage, to an aquatic system. One example is the "bloom" or great increase of
phytoplankton in a water body as a response to increased levels of nutrients. Negative environmental effects include
hypoxia, the depletion of oxygen in the water, which may cause death to aquatic animals.

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.
Eutrophication
The process by which a body of water acquires a high concentration of plant nutrients, especially nitrates or phosphates. This nutrification promotes algae growth that, when it dies, can lead to the depletion of dissolved oxygen, killing fish and other aquatic organisms. While eutrophication is a natural, slow-aging process for a body of water, human activities can greatly accelerate the process.
