A 2020 study reported that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse gases are cut. Warming in mesopelagic and deeper layers could have major consequences for the deep ocean food web, since ocean species will need to move to stay at survival temperatures. [66] [67]
The term "distilled vinegar" as used in the United States (called "spirit vinegar" in the UK, "white vinegar" in Canada [39]) is something of a misnomer because it is not produced by distillation, but by fermentation of distilled alcohol. The fermentate is diluted to produce a colorless solution of 5 to 8% acetic acid in water, with a pH of ...
The aquatic microbial loop is a marine trophic pathway which incorporates dissolved organic carbon into the food chain.. The microbial loop describes a trophic pathway where, in aquatic systems, dissolved organic carbon (DOC) is returned to higher trophic levels via its incorporation into bacterial biomass, and then coupled with the classic food chain formed by phytoplankton-zooplankton-nekton.
Water is the medium of the oceans, the medium which carries all the substances and elements involved in the marine biogeochemical cycles. Water as found in nature almost always includes dissolved substances, so water has been described as the "universal solvent" for its ability to dissolve so many substances.
The tiny marine cyanobacterium Prochlorococcus, discovered in 1986, forms today part of the base of the ocean food chain and accounts for more than half the photosynthesis of the open ocean [23] and an estimated 20% of the oxygen in the Earth's atmosphere. [24]

The microbial food web refers to the combined trophic interactions among microbes in aquatic environments. These microbes include viruses, bacteria, algae, heterotrophic protists (such as ciliates and flagellates). [1] In aquatic ecosystems, microbial food webs are essential because they form the basis for the cycling of nutrients and energy.
