Detailed explanation-1: -Obligate anaerobes, which live only in the absence of oxygen, do not possess the defenses that make aerobic life possible and therefore cannot survive in air.

Detailed explanation-2: -Aerobic bacteria refers to the group of microorganisms that grow in the presence of oxygen and thrive in the anoxygenic environment. Anaerobic bacteria refers to the group of microorganisms that grow in the absence of oxygen and cannot survive in the presence of an anoxygenic environment.

Detailed explanation-3: -Obligate aerobes live only in aerobic environments because they cannot survive without oxygen gas. Obligate anaerobes live only in anaerobic environments because oxygen’s byproducts are toxic to them. Facultative aerobes/facultative anaerobes can survive in both aerobic environments and anaerobic environments.
