eutrophication

[u″tro-fĭ-ka´shun]

the accidental or deliberate promotion of excessive growth (multiplication) of one kind of organism to the disadvantage of other organisms in the same ecosystem.

eutrophication

a process by which pollutants cause a body of water to become over-rich in organic and mineral nutrients, so that algae, CYANOBACTERIA and other microorganisms grow rapidly and deplete the oxygen supply.
