This is usually below the thermocline, which is a vertical zone in the water where temperature drops rapidly. The organisms that live in this region are called benthic organisms, and they are mostly detritivores, organisms which consume and recycle dead organic matter. Animals That Live in the Aphotic Region Tubeworms. 9. A comparison has been made between the present results and similar ones from experiments with other freshwater invertebrates (Table V, p. 35). The strong development of benthos in the profundal zone was attributed to a consistently large supply of food and warm (4 C) winter temperatures on bottom. This is because it is critical for wildlife habitat, water quality, and erosion control which are all important factors of a lake to have a healthy ecosystem.

Older lakes whose nutrient content is high and occupied by warm water fish. Why is the profundal zone important? A deep zone of an inland body of freestanding water, such as a lake or pond, is located below the range of effective light penetration. This is also where life basically started billions of years ago when amino acids started to form together in the water. Because phytoplankton populations are densest here, it is the zone most heavily responsible for oxygen production within the aquatic ecosystem.

The limnetic zone is the most photosynthetically-active zone of a lake since it is the primary habitat for planktonic species. Because these tiny plants carry on photosynthesis in open water, they are the base of the food chain upon which the rest of the limnetic life . The deepwater zone where sunlight hardly penetrates is known as a profundal or aphotic zone. The euphotic zone is the uppermost 80 meters (260 feet) or more of the ocean that is sufficiently illuminated to allow phytoplankton and plants to photosynthesise.

It is rich in nutrients and oxygen and is home to a variety of organisms. Many of these organisms feed on the detritus raining from the littoral zone. The profundal zone is a deep zone of an inland body of freestanding water, such as a lake or pond, located below the range of effective light penetration. Only heterotrophs (animals that eat dead organisms) are found in this zone. No green plants grow in the profundal zone because sunlight cannot reach this deep.
