Which term describes organisms that require oxygen to survive?

Explanation:
Organisms that require oxygen to survive rely on aerobic metabolism. In aerobic respiration, oxygen is the final electron acceptor in the electron transport chain, enabling the efficient production of ATP. This dependency on oxygen is what defines aerobes. The other terms describe cell structure rather than metabolic needs: prokaryotes are cells without a nucleus, and eukaryotes have a nucleus and organelles. Anaerobic organisms, by contrast, do not require oxygen and may rely on fermentation or anaerobic respiration instead.
