Microorganisms living in a marine environment
- 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.

Apr 21, 2022 · 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.
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 ).
ABSTRACT. Marine microbes are uniquely important to life as we know it. Since life most likely began in the oceans, marine microorganisms are the closest living descendants of the original forms of life. They are also major pillars of the biosphere.

The marine microbiome is composed of the three domains of life: bacteria, archaea, and eukarya, as well as viruses, all of which in dazzling numbers and diversity. All of the known microbial lineages are represented and many are exclusively found in the ocean and there is little doubt that life originated in the ocean. Download chapter PDF.
Jun 4, 2016 · Marine microscopic life varies from single-celled organisms, simple multicellular, to symbiotic microorganisms encompassing all three domains of life: Bacteria, Archaea and Eukarya as well as biologically active entities such as viruses and viroids. Together they form the Ocean’s “microbiome”.
