  • euphotic zone

Examples

  • During the summer, the euphotic regions of lakes become vibrant with plant life due to abundant sunlight and warm temperatures.

  • Species of Corallium exist below the euphotic zone at depths between 350 and 1,500 m, where temperature varies between 14 degrees and 3 degrees C. Resource management

    Academic text (1993)

  • All species lack symbiotic algae in their tissues (ahermatypic), and most are found in deep water below the euphotic zone (Table 4).

    Academic text (1993)

  • Primary production of plankton in the surface, illuminated (euphotic) zones of dry valley lakes is limited by the availability of nitrogen and phosphorus (Priscu 1995), which are at low concentrations despite the large pools of nutrients in deeper water (Tables 1 and 2).

    Academic text (1999)

  • Coral reefs thrive in the euphotic zone where sunlight penetrates the water, promoting the growth of symbiotic algae.

Morphology

euphotic = photic (semi-transparent) = eu + photic

Formally analyzable as eu- + photic, but both the Greek prefix 'eu-' and the adjective 'photic' are somewhat technical; the specific sense 'enough light for photosynthesis' is specialized and may not be obvious to average learners.

Etymology

Euphotic comes from the Greek parts eu- 'good' and phot- 'light', so it means 'well-lit'. Think of photo in photograph, which is about light; the euphotic zone is the 'well-lit' top layer of water where plants can make food with sunlight.
