Oxygen in the atmosphere is directly used in which process?
Answer and explanation
Correct answer: Respiration
During aerobic respiration, living cells use oxygen to oxidise food molecules and release usable energy, with carbon dioxide and water formed as products. This direct biological use makes respiration the correct process in option B. Photosynthesis generally uses carbon dioxide as a raw material and releases oxygen, condensation nuclei are usually tiny particles, and ultraviolet absorption is mainly associated with ozone rather than oxygen’s basic life-supporting role.
