What are the 3 zones of a lake?
A typical lake has three distinct zones (limnetic, littoral and the benthic zone; Fig.
11) of biological communities linked to its physical structure.
The littoral zone is the near shore area where sunlight penetrates all the way to the sediment and allows aquatic plants (macrophytes) to grow..
Why is littoral zone important?
The littoral zone is the area around the shoreline where the aquatic vegetation is and is required for most man-made lakes. 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.
Where is the littoral zone?
A littoral zone is the near shore area from the high water line to where the sunlight penetrates to the sediments in a waterbody. This zone may or may not contain plant life but it is the optimal region for aquatic plants to grow. Littoral zones are present in both fresh and saltwater environments.
What lives in the spray zone?
Organisms inhabiting this zone include, crabs, snails, mussels, and limpets. Finally, in the upper littoral zone, or spray zone, is dry the majority of the time, unless splashed with waves during high tide. Few organisms reside here, and include limpets, isopods, and barnacles.
What is meant by the littoral zone?
The littoral zone or nearshore is the part of a sea, lake, or river that is close 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. … (Lakes and rivers have their own definitions.)
What does littoral mean?
adjective. of or relating to the shore of a lake, sea, or ocean. (on ocean shores) of or relating to the biogeographic region between the sublittoral zone and the high-water line and sometimes including the supralittoral zone above the high-water line.
What are littoral countries?
Its littoral areas — including coastal regions of eastern India, Bangladesh, Sri Lanka, Myanmar, Thailand, Malaysia and Sumatra — are home to over half a billion people.
What are the littoral and benthic zones?
The littoral zone is the part of a body of water that is near the shore, while the benthic zone is the deepest area of a body of water, including some of the sediment. … For example, a few feet from the shore of a lake, the sediment can be considered to be in both the benthic and littoral zone.
What is the deepest zone in a lake?
profundal zoneThe 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. This is typically below the thermocline, the vertical zone in the water through which temperature drops rapidly.
What organisms live in the littoral zone?
Protected rocky shores are generally covered with seaweeds, mussels, barnacles, and so on, with various kinds of crabs and worms crawling among them. Protected sandy and muddy bottoms teem with burrowing mollusks, worms, and echinoderms.
What lives in the littoral zone of a lake?
The littoral zone is shallow and gets a lot of nutrients from runoff and non-point source pollution. Therefore, it typically has an abundance of aquatic plant and algae growth. Some other common inhabitants of the littoral zone are cattails, reeds, crawfish, snails, insects, zooplankton, and small fish.
