Microorganisms, or microbes, are tiny living organisms that are typically too small to be seen with the naked eye. They can exist as single-celled organisms or in colonies. The main types of microorganisms include:
- Bacteria: Single-celled organisms that can be found in various environments. They can be beneficial (like those in our gut) or harmful (pathogens).
- Archaea: Similar to bacteria but genetically distinct. They often thrive in extreme environments, such as hot springs and salt lakes.
- Fungi: Includes yeasts and molds. Fungi play essential roles in decomposition and nutrient cycling.
- Protozoa: Single-celled eukaryotic organisms that can be free-living or parasitic.
- Algae: Photosynthetic organisms found in water, which can be unicellular or multicellular.
- Viruses: Acellular entities that require a host cell to replicate and are not considered living organisms by some definitions.
Microorganisms are crucial for various ecological processes, including nutrient cycling, decomposition, and as part of the human microbiome, which supports health and digestion. They are also used in biotechnology, medicine, and food production.
