Microorganismen, also known as microorganisms or microbes, are living organisms that are too small to be seen with the naked eye. They are found in virtually every environment on Earth, from the deepest oceans to the highest mountains, and even within other living organisms. Microorganisms encompass a diverse range of life forms, including bacteria, archaea, fungi, protozoa, and microscopic algae.

These tiny entities play crucial roles in ecosystems. For instance, many bacteria and fungi are decomposers, breaking down dead organic matter and recycling nutrients, which is essential for plant growth. Others form symbiotic relationships with larger organisms. Microbes in the human gut, for example, aid in digestion and produce vitamins.

While some microorganisms are pathogenic and can cause diseases in humans, animals, and plants, the vast majority are harmless or even beneficial. Microbes are widely utilized in various industries, such as food production (fermentation for bread, cheese, and yogurt), medicine (production of antibiotics and vaccines), and environmental remediation (cleaning up pollution). Their study, microbiology, is a fundamental science with significant implications for health, agriculture, and biotechnology. The sheer abundance and metabolic diversity of microorganisms make them indispensable to life on our planet.
