The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, ...
Benthos (from Ancient Greek βένθος (bénthos) 'the depths [of the sea]'), also known as benthon, is the community of organisms that live on, in, or near the bottom of a sea, river, lake, or stream, also known as the benthic zone. [1]
All photosynthetic life needs light to grow and how far out into the ocean light can still penetrate through the water column to the floor or benthic zone is what defines the neritic zone. That photic zone , or area where light can penetrate through the water column, is usually above ~100 meters (~328 feet).
The benthic boundary layer (BBL) represents a few tens of meters of the water column directly above the sea floor [3] and constitutes an important zone of biological activity in the ocean. [4] It plays a vital role in the cycling of matter, and has been called the “endpoint” for sedimenting material, which fuels high metabolic rates for ...
Benthic-pelagic coupling are processes that connect the benthic zone and the pelagic zone through the exchange of energy, mass, or nutrients. These processes play a prominent role in both freshwater and marine ecosystems and are influenced by a number of chemical, biological, and physical forces that are crucial to functions from nutrient cycling to energy transfer in food webs.
Macrobenthos consists of the organisms that live at the bottom of a water column [1] and are visible to the naked eye. [2] In some classification schemes, these organisms are larger than 1 mm; [1] in another, the smallest dimension must be at least 0.5 mm. [3] They include polychaete worms, pelecypods, anthozoans, echinoderms, sponges, ascidians, crustaceans.
Meiobenthos, also called meiofauna, are small benthic invertebrates that live in marine or freshwater environments, or both. The term meiofauna loosely defines a group of organisms by their size—larger than microfauna but smaller than macrofauna—rather than by their taxonomy. This fauna includes both animals that turn into macrofauna later ...
The sixth season of the American adult animated television series Rick and Morty premiered on September 4, 2022. Starring Justin Roiland as both titular characters, Rick Sanchez and Morty Smith, and their inter-dimensional counterparts, the season was ordered before the fourth season of the show finished airing, in May 2020.
