There are various types of microorganisms, such as fungi, bacteria, protists, viruses, and archaea.
Microorganisms are a type of organism which is not visible to human eyes and hence called microscopic. There are various types of microorganisms, such as fungi, bacteria, protists, viruses, and archaea. Most of the microorganisms belong to the earliest life forms. Microbes can be parasitic or free-living. Many microorganisms are single-celled in other words, unicellular organisms. Microbes live everywhere on land, water, etc. Some of the microorganisms exist in the most extreme conditions and are called extremophiles. Microorganisms operate decomposition and hence are very vital in nutrient recycling. Even in the nitrogen cycle, microorganisms play a significant role. Not all microbes or microorganisms spread diseases. There are many which help in various natural processes and keep up the wellness of the ecosystem.
The microbes that live free obtain energy in various ways. Some adapt to photosynthesis, just like plants — some help in breaking down natural chemicals and produce energy. Most of them feed on dead things due to which the decaying happens.
We call certain microbes as germs because they cause diseases. Such microbes are called parasites that survive by taking upon other living things. Parasites cause mumps, measles, and chickenpox. Such parasites are known as viruses. Storing and properly preparing food can avoid microorganisms from manifesting and spreading diseases.
Microorganisms are omnipresent, and they are present in the food we eat, the air we breathe, the water we drink, the place we sit, stand, etc. They are cosmopolitan. They can even be present in the thermal geysers, vents, etc. (extremophiles).
Now, let us see various fields where microbes can help.
Bacteria help to treat sewage water from municipal waste. It uses anaerobic respiration, BOD, etc. to treat the water.
Methanogen bacteria help in the production of biogas.
Microbes in chemicals, enzymes, and other bioactive molecules:
Microbes are used in various parts of our day to day life, including some industries, and they are equally useful for nature.
Microorganisms or microbes have existed in nature for a very long time. Microbes have evolved quickly and have become useful for the environment as well as for living beings.The existence of both harmful and good bacteria provides a proper balance in the ecosystem. Microbes come under the bad category if they aid in spreading diseases and harming other living beings. Microbes come under good category if they help in various productions such as yeast, curd, and steroids so on. A lot of research work is done on the microbes, and various vaccines use microbes. There are innumerable uses of bacteria in the ecosystem, some of which may have not been found yet. Microbes are the backbone for production industries, especially food-related. Without microbes, the production of curd will cease to exist, and also bread will no longer be part of the food for living beings like humans. Hence bacteria have a bad side and a good side as well. The bad side has to stay under control, and the good side must not get exploited, which will keep a balance in the ecosystem.
