Role of Bacteria in Environment

Role of Bacteria in Environment
Bacteria are the unicellular organisms and cannot be seen with naked eye. There is no particular method of cell division, they simply divide simply by binary fission in which cell divides into two daughter cells. They do no have proper nucleus within the cell but the genetic material is attached to the cell membrane in an irregular form. They are found everywhere like top of the mountains, rivers, on land and in ice. Bacteria have the property of living in extreme weathers like extreme cold and extreme heat. They are able to live long because they become inactive for a long period of time.

Bacteria play an important role in the environment. Many dead materials are decomposed by bacteria. If there were no bacteria, the environment would have been polluted and full of harmful microorganisms. They degrade the dead organic matter and convert it into energy and nutrients. For example, they decompose trees and get their food from them in the form of nutrition.

Organic carbon present in the environment in the form dead organism is able to eat up all the carbon dioxide from the atmosphere if there were no decomposers in the on earth. It can be imagined that if carbon dioxide gets reduced from the atmosphere, there would have been no photosynthesis in plants and as a result no food would have been produced by plants. Decomposers or bacteria help in cycling of minerals like carbon and sulfur. They are also helpful in making, drugs, antibodies and hormones.

Nitrogen is the most important component of plants. Plants totally rely on nitrogen fro their health and growth and they cannot inhale it directly from the environment. They are dependent on soil for the supply of nitrogen. Through the process of nitrogen fixation, nitrogen from the atmosphere becomes available to the plants. This process takes place through bacteria for example Rhizobium and cyanobacteria. These species of bacteria convert the atmospheric nitrogen into nitrates and nitrites which is the part of their metabolism and make it available to the plants. Some plants have modified themselves so well that they are now able to store the bacteria into their tissues.

Using soil rich with beneficent bacteria can increase the productivity, growth and health of the plants. If carbon dioxide is the useful component of plants, similarly oxygen is also necessary for them because plants need oxygen in the process of respiration. They take oxygen by digesting the sugars present in them and use it for their growth. They absorb oxygen from the roots and if the roots will be able to absorb nutrients and energy from the soil only then they will be able to provide large amount of oxygen to the plants. Those soils are not fertile which do not have proper structure and organic matter. If these components will be present in the soil, then plants will get plenty of oxygen for respiration.

RE: Role of Bacteria in Environment
Bacteria and other microbes plays an important role in enviornment that is of DECOMPOSERS which acts in the last stage of food chain. These microorganisms like bacteria cause the breakdown of energy rich organic compounds. These compounds comes from decaying matter of plants such as leaves or from animals waste products and dead bodies.

The microbial mediated degradation process is also called bioremedation.

its a decomposer but that probaly doesnt help

RE: Role of Bacteria in Environment
Well,
Bacteria and other microbes play such an important role in our environment it's DE-Composers which acts in the last stage of food chain...

RE: Role of Bacteria in Environment
Bacteria plus other microbes plays an important character in environment that typically is of DE- COMPOSERS which acts with regard to the previous stage of food chain.

RE: Role of Bacteria in Environment
Yes thats true bacteria are found everywhere and they are also helpful for us.Take the simple example of Curd and Spices.They both contain bacteria and we all know that they are used in our daily routine.

RE: Role of Bacteria in Environment
Bacteria, indeed, have retained their predominant position and hold sway not only by virtue of a long and illustrious history but also for abundant reasons of contemporary vigor. Bacteria give yogurt its tangy flavor and sourdough bread its sour taste.

Bacteria, and other micro-organisms are essentially important in the cycling of nutrients and energy, particularly in the breakdown of dead organic matter to make the resources locked up in things like dead trees available again to other living organisms.

They also play a central role and the fixation of atmospheric Nitrogen into organic molecules and in the cycling of minerals such as Carbon and Sulfer. Bacteria also make, or help to make, drugs, hormones, or antibodies
