  • Front
  • Back
Photic Zone
Upper layer where light is sufficient for photosynthesis
Aphotic Zone
Recieve little light and no photosynthesis occurs
Thermocline
Narrow zone between warmer and colder waters where a rapid temperature change occurs
Littoral Zone
(Ponds and Lakes)
Shallow, well-lighted, warm water close to shore
Limnetic Zone
(Ponds and Lakes)
Open, well-lighted waters away from shore
Profundal Zone
(Ponds and Lakes)
deep, aphotic region
Oligotrophic lakes
Deep, nutrient-poor and do not contain much life.
-Water is usually clear.
-Profundal zone has high O2 since little detritus is produced in limnetic zone.
Eutrophic lakes
shallower and have increased nutrients
-Waters are usually murky due to large phytoplankton populations and large amounts of detritus being decomposed--> O2 depletion in profundal zon during summer.
Pelagic Zone
(Marine Biomes)
Open waters of any depth
Benthic Zone
(Marine Biomes)
Sea floor
Intertidal Zone
(Marine Biomes)
Shallow zone where the terrestrial habitat meets ocean waters
Neritic Zone
(Marine Biomes)
From intertidal to edge of continental shelf
Oceanic Zone
(Marine Biomes)
Beyond continental shelf
