Which atmospheric component plays a role in both photosynthesis and the greenhouse effect?
Answer and explanation
Correct answer: Carbon dioxide
Carbon dioxide has two relevant roles. Green plants take it from the air as a carbon source during photosynthesis and use light energy to form carbohydrates, releasing oxygen as a by-product. At the same time, atmospheric carbon dioxide absorbs outgoing infrared radiation and contributes to the greenhouse effect. Thus option A is correct. Argon and neon are inert gases, while dust is not the atmospheric gas described here.
