The aquatic food linkage between heterotrophic bacteria and protists is so-called “microbial loop”, functioning as important matter cycling in pelagic food webs of

35 relations. The microbial loop in flowing waters is dependent on allochthonous sources of carbon, which vary in quality. The proportion of dissolved organic carbon (DOC) that can be degraded ranges from <1 to over 50%, and the bioavailability of DOC (micrograms bacterial biomass produced per milligram DOC present) ranges over two orders of magnitude. Microfaunal stimulation of nitrogen mineralization via the microbial loop was suggested as the main underlying mechanism (Clarholm, 1985; Griffiths, 1994; Zwart et al., 1994). Table 1.

These members of the plankton also leak DOM that is in turn absorbed by the bacteria. The bacteria are decomposers and release inorganic nutrients for uptake by phytoplanktons. It is estimated that 60 percent of the energy flowing through marine food chains passes through the microbial loop The microbial loop is the conventional model by which nutrients and minerals are recycled in aquatic eco-systems. Biochemical pathways in different organisms become metabolically inter-connected such that nutrients are utilized, processed, released and re-utilized by others. The microbial loop is so important, scientists view it as the microbes’ most essential ecological role. Transformational Power Instead of sunlight, specialized organisms can obtain energy through chemical reactions, a process called chemosynthesis.

av I Sundberg · 2004 · Citerat av 4 — Thus, the microbial loop, where also bacteria and other picoplankton are important actors, may be at least as important as macro- zooplankton, e.g. in the 

The final link in all food chains is made up of decomposers, those heterotrophs that break down dead organisms and organic wastes.

The microbial loop is known as the pathway for dissolved organic matter (DOM) through the bacterial and microzooplankton communities to higher trophic levels  

 The final link in all food chains is made up of decomposers, those heterotrophs that break down dead organisms and organic wastes.  A food chain in which the primary consumer feeds on living plants is called a grazing pathway.
