Marine animals share the sea with a vast diversity of microorganisms, including protists, bacteria, archaea, fungi, and viruses which comprise millions of cells in each milliliter of the 1.3 billion km 3 of water comprising the oceans (Eakins and Sharman, 2010).
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.

There are many types of marine microbes. These include bacteria, which you can also find on land. Most bacteriaare single-celled organisms. That means their bodies are made up of only one cell. In the ocean, bacteria support many chemical processes, including photosynthesis. Phytoplanktonare another group of marine microbes. These microscopic creat...
A food chaindescribes the relationship between organisms that eat other organisms. Plants are the base of land food chains. For example, cows eat grass. Then some people eat cows. Phytoplankton are the base of ocean food chains. They get their energy from the sun. Then, on the next level of the food chain, zooplanktoneat phytoplankton. Zooplankton ...
Cyanobacteria are a common type of marine bacteria. They are also a type of phytoplankton. That means they produce their own food through photosynthesis. Many cyanobacteria are also an important part of the nitrogen cycle. They convert nitrogen to a form that other marine organisms can use. Marine bacteria also help clean up ocean pollution. Some b...
It’s not easy for scientists to study marine microbes. Only 1% of marine bacteria can be grown in a laboratory. So scientists have to study them in the ocean. The tiny size of bacteria makes this very hard. Scientists sometimes collect microbes using plankton nets. These cone-shaped nets have a very fine mesh. A container at one end of the net coll...
Marine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism (or microbe) is any microscopic living organism or virus, which is invisibly small to the unaided human eye without magnification ...
Sep 1, 2019 · Marine microorganisms may attach to plants and animals inhabiting the ocean, exist in symbiotic relationships within animal intestines or plant issues according to their benefit or convenience, or exist in parasitic or predatory relationships.
