Microorganisms, commonly referred to as microbes, are microscopic life forms that inhabit diverse environments across the globe. These include bacteria, viruses, fungi, and protozoa, among others. Despite their microscopic size, these organisms play a significant role in the sustenance of life on Earth. They are involved in various processes, including nutrient cycling, decomposition, and the formation of different habitats. The study of these organisms forms the basis of microbial ecology, a field that seeks to understand the role and significance of these tiny entities in our world.
