The scientific field that focuses on the study of microorganisms is microbiology. This branch of biology encompasses various types of microbes, including bacteria, viruses, fungi, and protists. Microbiologists explore the roles of these organisms in ecosystems, human health, industrial processes, and biotechnology, providing invaluable insights into the essential functions they perform. Understanding microorganisms helps in disease prevention, developing antibiotics, and utilizing microbes in applications such as fermentation and bioremediation, thereby impacting multiple aspects of life.
