What are retrospectives and why are they important? 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. Low oxygen levels are characteristic of the profundal zone due to the accumulation of decaying vegetation and animal matter that rains down from the pelagic and benthic zones and the inability to support primary producers. Everything from deceased fish and animals to dead plants, or animal droppings. Neritic Zone: Definition, Animal Life, and Characteristics - ThoughtCo It sustains diverse biodiversity, which includes various species of algae, floating plants, submerged plants and phytoplankton.

The lowest point in the resting metabolism in the daily cycle and the maximum steady rate of oxygen uptake found when the fish were stimulated to activity in a rotating chamber were measured. Approximately 1% of the Earths surface is covered with fresh water; however, 40% of known fish species inhabit freshwater. littoral zone, marine ecological realm that experiences the effects of tidal and longshore currents and breaking waves to a depth of 5 to 10 metres (16 to 33 feet) below the low-tide level, depending on the intensity of storm waves. Though some do live 20-30 years. Dominant are the phytoplankton and among them the diatoms, the desmids and the filamentous green algae. In marine profundal zones echinoderms such as sea urchins, and crustaceans such a a few species of crabs, are also found. profundal zone. This zone extends at a depth where sunlight penetrates. However, the meaning of littoral zone can extend well beyond the intertidal zone. 2022 VS Imveis. Most benthos feed on food as it floats by or scavenge for food on the ocean floor. The aphotic zone exists in depths below 1,000 meters (3,280 feet). Low levels of photosynthesis leads to low levels of oxygen. The aphotic zone (aphotic from Greek prefix - + "without light") is the portion of a lake or ocean where there is little or no sunlight. eNotes Editorial, 22 Sep. 2011, https://www.enotes.com/homework-help/what-lives-in-the-profundal-zone-list-the-biotic-279369.

Freshwater lakes are natural bodies of water formed due to rainfall, melting snow, or groundwater seepage in the Earths surface. Conversely, eutrophic, or old, bodies of water have wide Littoral Zones because of their gentle sloping shoreline and sides. There are also large quantities of decomposers and duckweed, species diversity. This zone is the most productive since it gets abundant energy from sunlight and absorbs nutrients from land run-off. This zone, of course, ranges from the shallow depths where water meets land, to extreme depths that humans have . Because food is so rare thus far down in the water, the creatures that dwell in this zone will consume everything they come across. It was shown that the animals from one of the fresh water localities have a smaller oxygen consumption than animals from brackish water, which is connected with reduced growth of the freshwater animals, and from another fresh water locality the oxygen consumption is, on the other hand, a little bigger than the oxygen Consumption for the brackist water animals.
