Exhaustive and meticulous studies have provided a substantial evidence that the
habitat
microbe’s or an animal’s or plant’s natural environment) of a
microorganism is extremely vital and
important in the precise and definitive characterization of that particular organism.
Examples:
(
a) Microbes in Buccal Cavity: The population of the microorganisms present in the buccal
cavity
(or oral cavity) distinctly differs from that of the gastrointestinal tract (GIT).
(
b) Marine Microorganisms: Invariably the microorganisms located specifically in the marine
environments
differ predominantly from those found in the fresh water and terrestrial environments.
(
c) Distribution in Nature: Quite often one may observe that certain microorganisms are abundantly
and widely distributed in nature, whereas others, may be significantly restricted to a
specific environment.
Besides, a number of vital factors, such as : life-cycle patterns, the nature of
symbiotic** relationships,
the capability for causing disease in a specific host, and preferential habitats
e.g., pH, O2,
temperature, osmotic concentration, do represent other befitting examples of
taxonomically importantecological characteristic features.
