CHEMISTRY [1 Mark Question Answer]

Photosynthesis removes carbon dioxide naturally — and trees are especially good at storing carbon removed from the atmosphere by photosynthesis

Oxygen is used for combustion and respiration but we release CO2 . Plants take in carbon dioxide and give out oxygen. Hence, the amount of oxygen remains the same.

Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light. These molecules are invisible because when you stretch one, it doesn’t change the electric field.
