Protists are usually one-celled microorganisms. They include algae ( autotrophs which make their own food) and protozoans ( heterotrophs which eat the algae for food). In recent years, researchers have discovered many protists are mixotrophs, which can function in both modes. Marine protists are defined by their habitat as protists that live in ...
Marine microbiome. Marine animal host-microbiome relationship. Relationships are generally thought to exist in a symbiotic state, and are normally exposed to environmental and animal-specific factors that may cause natural variations. Some events may change the relationship into a functioning but altered symbiotic state, whereas extreme stress ...

What is the role of protists in marine biogeochemical cycles?
Marine prokaryotes are responsible for significant levels of the photosynthesis that occurs in the ocean, as well as significant cycling of carbon and other nutrients. Prokaryotes live throughout the biosphere. In 2018 it was estimated the total biomass of all prokaryotes on the planet was equivalent to 77 billion tonnes of carbon (77 Gt C ...
Danielle Hall. Reviewed by Alyson Santoro and Sarah Laperriere, UC Santa Barbara. Invisible to the naked eye, there is a teeming world of microbes living in the ocean with a complexity and diversity that rivals all other life on Earth. They include bacteria, viruses, archaea, protists, and fungi.
Feb 28, 2022 · Abstract. Diversity within marine microbiomes spans the three domains of life: microbial eukaryotes (i.e., protists), bacteria, and archaea. Although protists were the first microbes observed by microscopy, it took the advent of molecular techniques to begin to resolve their complex and reticulate evolutionary history.
Apr 15, 2021 · Interpolated average (2005–2017) SSS data (0.25° grid resolution) generated using gliders, oceanographic casts and other methods from the 2018 World Ocean Atlas 66 were parsed to include only ...
Ocean microbes play an important role in Earth's biogeochemical cycles, particularly the carbon, nitrogen, phosphorus, iron, and sulfur cycles. They also form the very base of the marine food chain, recycle nutrients and organic matter, and produce vitamins and cofactors needed by higher organisms to grow and survive.
