Microbiologists place bacteria in the following major catogories:

Explanation

Eubacteria and Archaebacteria are the two main domains of prokaryotic organisms.Eubacteria are the most familiar type of bacteria that live in a wide range of habitats, including soil, water, and human bodies. They have a cell wall made of peptidoglycan, which makes them structurally different from Archaea.archaea, on the other hand, are a unique group of prokaryotes that have distinct characteristics from eubacteria. They were once classified as a type of bacteria, but later studies showed that they are more closely related to eukaryotes. Archaea can live in extreme environments, such as hot springs, hydrothermal vents, and salty lakes.
