What is the difference between a strict anaerobe and a facultative anaerobe?

ANSWER: Strict anaerobes cannot utilize oxygen as a final acceptor and generally live in oxygen free
environments; therefore, they carry out fermentation. Facultative anaerobes can switch
between fermentation and full oxidative pathways depending on oxygen supply.
