Planting more and more trees helps to: — Qualitative and Quantitative Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Plants undergo photosynthesis, absorbing carbon dioxide (CO2) from the atmosphere and releasing oxygen (O2) gas. Step 2: Afforestation or planting more trees acts as a sink for CO2, reducing its level in the atmosphere, while simultaneously enriching the air with O2. Step 3: Therefore, planting trees helps to reduce CO2 and increase O2 in the air, corresponding to option (d).
