Bacteria are accountable for the decomposition procedure at the end of food chains and food webs; in this procedure, they as well liberate utile gases and nutrients for other living-beings. Bacteria which live in the digestive tube of ruminants and of certain insects digest cellulose for such animals. Various bacteria as well participate in the nitrogen cycle, forming fixation of nitrogen, nitrification and de-nitrification, nearly always in mutualist ecological interaction with the plants. Bacteria present in living-beings, for illustration, some that live within the bowels, compete with another pathogenic bacterium therefore controlling the population of noxious agents. There are as well bacteria which cause diseases and bacteria employed in the production of medical drugs.

Mass destruction or Excessive proliferation of bacteria can impact whole ecosystems. For illustration, whenever a river is polluted by organic material the population of aerobic bacteria raises as the organic material is food for them; the big number of bacteria then exhausts the oxygen which is dissolved in water and other aerobic beings (such as fishes) undergo mass death.
