The bacteria are then consumed by flagellates and ciliates. These members of the The microbial loop Last Updated on Thu, 17 Dec 2020 | Marine Ecology In the marine ecosystem the foregoing elementary account of the organic food cycle must be extended to take account of the significance of dissolved organic matter (DOM) in seawater. Answering Charles Darwin’s prescient question has taken us nearly two centuries. Only in recent decades have methods and concepts been developed to explore the significance of microbes in the ocean’s web of life. Microbial loop This important part of marine food chains involves DOM leaked from diatoms and other phytoplankters that is consumed by bacteria. The bacteria are then consumed by flagellates and ciliates. These members of the The microbial loop describes a trophic pathway in the marine microbial food web where dissolved organic carbon (DOC) is returned to higher trophic levels via its incorporation into bacterial biomass, and then coupled with the classic food chain formed by phytoplankton - zooplankton - nekton.

Transformational Power. Instead of sunlight, specialized organisms can obtain energy through chemical reactions, a process called chemosynthesis. The microbial loop is known as the pathway for dissolved organic matter (DOM) through the bacterial and microzooplankton communities to higher trophic levels. This pathway is considered important for carbon and nitrogen transport in the pelagic environment (Azam et al., 1983).
