[89] [90] Studies have shown high protist diversity exists in oceans, deep sea-vents and river sediments, suggesting a large number of eukaryotic microbial communities have yet to be discovered. [ 91 ] [ 92 ] There has been little research on mixotrophic protists, but recent studies in marine environments found mixotrophic protests contribute a ...
Prokaryotes play important roles in ecosystems as decomposers recycling nutrients. Some prokaryotes are pathogenic, causing disease and even death in plants and animals. [5] 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. [6]

This is a list of seas of the World Ocean, including marginal seas, areas of water, various gulfs, bights, bays, and straits. [2] In many cases it is a matter of tradition for a body of water to be named a sea or a bay, etc., therefore all these types are listed here.
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Many species of marine fungi are known only from spores and it is likely a large number of species have yet to be discovered. [3] In fact, it is thought that less than 1% of all marine fungal species have been described, due to difficulty in targeting marine fungal DNA and difficulties that arise in attempting to grow cultures of marine fungi.

Prime decomposers are bacteria or fungi, though larger scavengers also play an important role in decomposition if the body is accessible to insects, mites and other animals. Additionally, [ 3 ] soil animals are considered key regulators of decomposition at local scales but their role at larger scales is unresolved.
[2] [3] The name Aquificota was given to this phylum based on an early genus identified within this group, Aquifex (“water maker”), which is able to produce water by oxidizing hydrogen. [4] They have been found in springs, pools, and oceans. They are autotrophs, and are the primary carbon fixers in their environments.
