The biota of the rumen are found in about equal biomasses of bacteria (1011 cells / that lignin is not broken down when oxygen is absent). Introduction: Microbes perform better functions for agricultural production by promoting various direct and indirect mechanisms in soil and plants. Fungi are uncommon in aquatic environments. It moves in the soil rapidly and is acted upon by microorganisms of the category of chemosynthetic autotrophs in the soil. About half the plants have viruses, but most don't seem to be sick at all. The phenomenon of nitrogen fixation takes place by special type of bacteria which fix free atmospheric nitrogen gas into ammonia by means of symbiosis with leguminous plants.
