Which term describes organisms that require oxygen to live?

• A. Anaerobic Organism
• B. Aerobic Organisms
• C. Non-Pathogenic Organism
• D. Pathogenic Organism

Answer: (B)

Organisms that require oxygen to live are called aerobic. This term describes the demand for oxygen in their energy-producing processes; aerobic organisms rely on oxygen for cellular respiration to generate ATP, typically producing more energy per glucose than anaerobic routes. The other terms don’t describe how they use oxygen: anaerobic organisms do not need oxygen and may even be harmed by it; non-pathogenic and pathogenic refer to whether an organism can cause disease, not its oxygen requirement.
