Answer 1

The component of air used by green plants to make their food is Carbon dioxide.

• The process in which Carbon dioxide and water in the presence of sunlight and chlorophyll release Glucose and Oxygen is called photosynthesis. Through this process, plants prepare their own food.

$\underset{\mathrm{Carbon}\mathrm{Dioxide}}{6{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Water}}{6{\mathrm{H}}_2\mathrm{O}}\left(\mathrm{l}\right)\underset{\mathrm{Chlorophyll}}{\overset{\mathrm{sunlight}}{\to }}\underset{\mathrm{Glucose}}{{\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6}\left(\mathrm{aq}\right)+\underset{\mathrm{Oxygen}}{6{\mathrm{O}}_2}\left(\mathrm{g}\right)$

Therefore, the component of air used by green plants to make their food is Carbon dioxide.
