Solution

The correct option is D Photosynthesis
The process of taking in CO $_{2}$ by plants and releasing O $_{2}$ is occurs in photosynthesis. Photosynthesis is the process by which green plants prepare their own food from CO $_{2}$ and water using the energy from the sunlight. Glucose is formed in this process which acts as food for the plants. Reaction of photosynthesis is:
6 CO $_{2}$ + 6 H $_{2}$ O $\to$ C $_{6}$ H $_{12}$ O $_{6}$ + 6 O $_{2}$
So, the correct answer is option D.

Plants use CO₂ for photosynthesis during the day . But at night , they also respire ,i.e.,take in O₂ and release CO₂ into the air . This doesn't help much in the reduction of CO₂ . Then why do people ask to plant more trees ? Is there a more effective method to reduce CO₂ in the air ?
