Microorganisms are tiny living organisms, including bacteria, viruses, fungi, and protozoa, that are often invisible to the naked eye. They exist everywhere in soil, water, air, and even inside the human body. While some microorganisms cause diseases, many are beneficial, playing essential roles in processes such as digestion, nutrient cycling, and the production of foods like yogurt, cheese, and antibiotics.
Studying microorganisms helps scientists understand health, ecology, and biotechnology. Microbiology enables the development of vaccines, medicines, and industrial applications, as well as monitoring environmental changes and controlling infectious diseases. By understanding microorganisms, humans can harness their benefits while minimizing harmful effects, improving both health and the environment. Shutdown123
