Örverurnar

Örverurnar is an Icelandic term that translates to "microbes" or "microorganisms." It broadly encompasses a diverse group of living organisms that are too small to be seen with the naked eye. This category includes bacteria, archaea, viruses, fungi (like yeasts and molds), and single-celled eukaryotes such as protozoa. Örverurnar are found in virtually every environment on Earth, from the deepest oceans and hottest springs to the soil, air, and even within other living organisms.

These tiny life forms play crucial roles in ecosystems and biological processes. They are essential for nutrient cycling, breaking down organic matter, and forming the base of many food chains. In agriculture, they are vital for soil fertility. Many örverurnar are also beneficial to humans and animals, aiding in digestion, producing vitamins, and defending against harmful pathogens. Conversely, some örverurnar are pathogenic, causing diseases in plants, animals, and humans. The study of örverurnar is known as microbiology.
