What are Microorganisms?
Definition of microorganisms – Microorganisms, or microbes, are microscopic life forms that are ubiquitous in nature. They can be unicellular or multicellular.
Microorganisms are extremely small life forms that are not visible to the naked eye. They can be seen only thorough a microscope. Other than macroscopic life forms such as plants and animals, microbes constitute one of the most important parts of biological systems on the planet. The diverse group of microbes comprises viruses, bacteria, fungi, protists, and algae.
They inhabit air, water, soil, and even living organisms. They thrive in extreme ecosystems such as thermal vents, highly acidic or alkaline environments, and salinity as well. This unseen domain plays a very crucial role in bringing life to earth. Microorganisms are our friend and foe. On one side, microbes in human welfare are beneficial for us, but on the other side, they can be harmful in many diverse ways.
Microorganisms – Useful And Harmful
Microorganisms are microscopic life forms that are ubiquitous. They can be unicellular or multicellular and are beneficial to humankind, but they can be harmful as well. Microbes can be beneficial as they play diverse roles in nutrient cycling, food fermentation, antibiotic production, and many more.
On the other hand, they are also responsible for causing diseases in humans and animals, food spoilage, and posing environmental challenges. Microorganism examples are bacteria, protozoa, algae, and fungi.
