the beauty of tiny invisible thingies

As 7K entered the world of invisible it was dazzled by the beauty of microorganisms. Microorganisms so tiny and small but combine an universe that covers all of the surface of the earth. Microorganisms /Greek: μικρός, mikrós, meaning small and ὀργανισμός, organismós, meaning organism; also spelled micro organism or micro-organism/ or microbes are organisms that are microscopic, too small to be seen by the naked human eye. Their diverse universe includes bacteria, fungi, archaea, and protists; microscopic plants /green algae/; and animals such as plankton and the planarian. Some microbiologists also include viruses, but others consider these as non-living. Most microorganisms are unicellular, single-celled, but this is not universal, since some multicellular organisms are microscopic, while some unicellular protists and bacteria are macroscopic and visible to the naked eye.
Microorganisms live in all parts of the biosphere where there is liquid water, including soil, hot springs, on the ocean floor, high in the atmosphere and deep inside rocks within the Earth’s crust. Microorganisms are vital to humans and the environment, as they participate in the Earth’s element cycles such as the carbon cycle and nitrogen cycle, as well as fulfilling other vital roles in virtually all ecosystems, such as recycling other organism’s dead remains and waste products through decomposition. Microbes also have an important place in most higher-order multicellular organisms as symbionts and are also exploited by people in biotechnology, both in traditional food and beverage preparation, and in modern technologies based on genetic engineering.
