The profundal zone is the deepest and darkest zone of a lake, where sunlight does not penetrate. It is characterized by low levels of oxygen, limited plant growth, and a large amount of organic matter that has sunk to the bottom. Organisms adapted to low-light conditions, such as deep-water fish and detritus-feeding organisms, are commonly found in this zone.

Is the zone of saturation above the zone of aeration?
No, the zone of saturation is below the zone of aeration in the ground. The zone of saturation is where all spaces between soil particles are filled with water, while the zone of aeration is where there are air pockets between the soil particles.
What can be found where a river enters a lake?
At the point where a river enters a lake, you may find a delta formed by sediment deposition, creating a complex network of channels and wetlands. This area is typically rich in biodiversity, supporting a variety of plant and animal species that thrive in the transition zone between the flowing river and calm lake waters. The mixing of different water types can also create unique habitats for aquatic life.
Is the zone of aeration above the zone of saturation?
Yes, the zone of aeration is located above the zone of saturation. The zone of aeration contains spaces filled with both air and water, whereas the zone of saturation is where all available spaces are filled with water.
Is Lake Michigan considered a sea or is it classified as a lake?
Lake Michigan is classified as a lake, not a sea.
Is Lake Erie freshwater or saltwater?
Lake Erie is a freshwater lake.
Describe the three zones of a lake?
Littoral Zone - In coastal environments and biomes, the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged. It always includes the intertidal zone and is often used to mean the same as the intertidal zone. However, the meaning of "littoral zone" can extend well beyond the intertidal zone. Limnetic Zone - The limnetic zone is the well-lit, open surface waters in a lake, away from the shore. The vegetation of the littoral zone surrounds this expanse of open water and it is above the profundal zone. Profundal Zone - The profundal zone is a deep zone of a body of water, such as an ocean or a lake, located below the range of effective light penetration. This is typically below the thermocline, the vertical zone in the water through which temperature drops rapidly. The lack of light in the profundal zone determines the type of biological community that can live in this region, which is distinctly different from the community in the overlying waters. The profundal zone is part of the aphotic zone
What is the definition of deep-water zone?
Close to the the marine's benthic zone, this zone is the bottom-most zone to the fresh water biome.
Does plants in lakes grow in the profundal zone?
Sunlight doesn't reaches this zone so no plants are able to grow.
A lake in which minerals are scarce is profundal oligotrophic eutrophic benthic pelagic?
Found it. Its oligotrophic.
What is the difference between littoral zones and limnetic zones?
The littoral zone is that part of a sea, lake or river that is closest to the shore. In coastal environments, the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged. The limnetic zone is the well-lit, open surface waters in a lake, away from the shore. The vegetation of the littoral zone surrounds this expanse of open water. The limnetic zone is found just above the profundal zone. Most of a lake's photosynthesis takes place in the limnetic zone.
What is portion of the marine biome that is shallow enough for sunlight to penetrate called?
Sunlight can penetrate through the limnetic zone into the profundal zone.
Which zone has the most plankton Profundal Littoral or Limnetic?
The Limnetic zone should have the most plankton, as it is the section with the best suitable conditions for organisms to thrive. The Limnetic zone is wide opened to sunlight, and is also oxygen filled. However the profundal zone has a very limmited supply of oxygen and sunlight, which makes the water cold and harder for organisms, such as plankton to thrive there.
A water body with 2.5m depth and 3000 square meters area is considered to be a pond or a lake?
From the wikianswers: "Scientifically, a pond is any man made body of water where light is found in the entire pond body of water. A lake is any body of water that has a profundal-zone http://www.answers.com/topic/profundal-zone Hence a water body of depth 2.5 m can at best be called as a pond only. The nature of construction of the water body is given in the question. If it is a masonry/concrete construction it can be called a as sump/tank/reservoir as well. Usually ponds and lakes have natural ground as the base. Gopalakrishnan.P
What is the temperature in the photic zone?
This depends largely on which body of water we're talking about. The temperature of the photic zone in the arctic is definitely different that that of the tropics. What we can say is that due to the allowance of light, it is warmer than the aphotic (profundal) zone.
What type of food is eaten in each zone of a lake?
In the littoral Zone its Sea weed, Limnetic Zone is Bitts of Chloropholic Plants, Euphotic Zone its clams or shrips that flote around. & Benthic Zone you find pizza, and hotdogs and chips and and if you're really lucky you'll find a Mc,Chicken with a spongbob toy inside you're happymeal. :D
Which lake zone would be absent in a very shallow lake?
limnetic zone
Where does the open-water zone of lake end?
