Plants use the process of to remove carbon dioxide from the air.

The correct answer for the blank is- Photosynthesis.

Photosynthesis is a process of formation of food ( that is glucose, a  carbohydrate) by green plants and algae.

In this process, green pigment ( chlorophyll) absorbs energy from sunlight in presence of water and carbon dioxide ( which is present in the atmosphere), and convert it into chemical energy ( ATP and NADPH), which is used in the formation of glucose. Oxygen is released in the surrounding ( by splitting of water molecule) in this process.

Thus, plants use the process of photosynthesis to remove carbon dioxide from the air.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
