Why is atmospheric oxygen considered a link between life and energy processes?
Answer and explanation
Correct answer: Because it takes part in both respiration and combustion
Oxygen connects biological energy release with several physical and chemical energy processes. In aerobic respiration, organisms use oxygen to oxidise food molecules and release usable energy for life activities. Oxygen also supports combustion, in which fuels react rapidly and release heat and light. Thus option B correctly identifies both roles. The other options describe no genuine atmospheric function of oxygen.
