Step-by-step solution

ARCHAEBACTERIA: These archaebacteria are special since they live in some of the harshest habitats such as extreme salty are as (halophiles), h ot springs (thermoacidophiles), and marshy areas (methanogens). Archaebacteria differ from other bacteria in having a different cell wall structure and this feature is responsible for their survival in extreme conditions. Archaebacteria are divided into three groups - methanogens, halophiles, and thermoacidophiles. Methanogens: These bacteria are of marshy habitats. They are
