Verified step by step guidance

Understand the definitions of each type of organism in relation to oxygen: Aerotolerant anaerobes, Facultative anaerobes, Obligate aerobes, and Microaerophiles.

Aerotolerant anaerobes do not require oxygen for growth but can tolerate its presence. They use fermentation to produce energy.

Facultative anaerobes can grow with or without oxygen. They use aerobic respiration when oxygen is present and switch to fermentation or anaerobic respiration when it is absent.

Obligate aerobes require oxygen for growth as they rely on aerobic respiration to produce energy.

Microaerophiles require oxygen but at lower concentrations than are present in the atmosphere. They are sensitive to high oxygen levels.
