Why is atmospheric carbon dioxide balance determined by both emissions and absorption?
Answer and explanation
Correct answer: Because vegetation and oceans remove or store carbon dioxide
The governing idea is the balance between carbon sources and carbon sinks. Burning fuels, respiration and land-use change add carbon dioxide, while photosynthesis, ocean uptake and long-term storage remove or retain part of it. The atmospheric amount depends on the difference between these opposing flows, so option A is correct. The other choices deny emissions, falsely set carbon dioxide to zero, or assign carbon storage to ozone.
