The active release of reactive oxygen species from cells has a variety of purposes, including a means to deter predators, or a chemical defense for the incapacitation of competitors. [ 58 ] [ 59 ] [ 60 ] In addition, ROS may be involved in cell signaling, as well as the oxidation or reduction of necessary or toxic metals.
Aquatic photosynthesis is the occurrence of photosynthesis in the aquatic environment, which includes the freshwater environment and the marine (saltwater) environment. . Organisms that perform photosynthesis in the aquatic environment include but are not limited to plants, algae, cyanobacteria, [1] coral, [2] phytoplankton (also known as micro
A deep-water oxygenation system could be in the cards for Lake Hopatcong, New Jersey's largest lake, as stakeholders seek to stifle the kind of harmful algal blooms that effectively closed it in 2019.
The organisms responsible for primary production are called primary producers or autotrophs. Most marine primary production is generated by a diverse collection of marine microorganisms called algae and cyanobacteria. Together these form the principal primary producers at the base of the ocean food chain and produce half of the world's oxygen ...
Bluegill were among the species of fish tested in Michigan. Fourteen different PFAS chemicals were detected, with a range of 11,000 to 133,000 parts per trillion. One chemical in particular, known ...
Microalgae play a major role in nutrient cycling and fixing inorganic carbon into organic molecules and expressing oxygen in marine biosphere. While fish oil has become famous for its omega-3 fatty acid content, fish do not actually produce omega-3s, instead accumulating their omega-3 reserves by consuming microalgae. These omega-3 fatty acids ...
Climate change is going to wreak havoc on the world’s oceans, according to two new studies, depleting the warming waters of the oxygen that fish and other sea life need to survive.
The word oxygen in the literature typically refers to molecular oxygen (O 2) since it is the common product or reactant of many biogeochemical redox reactions within the cycle. [37] Processes within the oxygen cycle are considered to be biological or geological and are evaluated as either a source (O 2 production) or sink (O 2 consumption). [36 ...
