Question

Name a process which removes carbon dioxide from the air.

Answer 1

The process which is used to remove Carbon dioxide from the air is photosynthesis.

Photosynthesis:

• The process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water is called photosynthesis.
• Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. In this process, carbon dioxide is taken up by the plant and fixed in the form of glucose.

$$\begin{gathered} 6{\mathrm{CO}}_2\left(\mathrm{g}\right)+12{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\underset{\mathrm{chlorophyll}}{\overset{\mathrm{sunlight}}{\to }}{\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\left(\mathrm{s}\right)+6{\mathrm{O}}_2\left(\mathrm{g}\right)+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ \mathrm{Carbon}\mathrm{dioxide}\mathrm{Water}\mathrm{Glucose}\mathrm{Carbon}\mathrm{dioxide}\mathrm{Water} \end{gathered}$$
