Examples

  • The increased algal blooms and decreased oxygen supplies in eutrophic waters can have detrimental effects on fisheries and other aquatic populations.

    Academic text (1994)
  • For example, in a eutrophic lake sediment, microbes may break down phytoplankton and macrophytes, releasing phosphorus.

    Academic text (2000)
  • Eutrophication. Lakes and streams can become eutrophic due to excessive inputs of nutrients (nitrogen and/or phosphorus) from point or non-point sources.

    Academic text (2000)

Morphology

eutrophic = trophic (semi-transparent) = eu + troph + ic

The prefix 'eu-' means 'good' or 'well', but the specific ecological context of 'eutrophic' is specialized.

Etymology

Eutrophic comes from Greek parts eu- 'good' and troph 'food'. So a eutrophic lake is like a 'well-fed' lake full of nutrients, which makes lots of algae and plants grow and can lower the water's oxygen.
