Why is carbon dioxide not considered fully constant despite its small amount in dry air?
Answer and explanation
Correct answer: Its amount changes due to human activities and natural processes
The governing concept is atmospheric variability and the carbon cycle. Carbon dioxide is released by respiration, decomposition, combustion, volcanic activity, and industry, while plants and oceans remove or absorb part of it through photosynthesis and exchange. Consequently, its concentration changes with place, season, and human activity, so option A is correct. The other options describe impossible or opposite processes.
