Andrej [43]

We can decrease overall atmospheric CO2 by increasing photosynthesis rate or reducing cellular respiration.

<h3>What is cellular respiration?</h3>

Cellular respiration is a process by which aerobic cells can produce energy and carbon dioxide by using the chemical energy of foods and oxygen.

Conversely, photosynthesis produces carbohydrates and oxygen by using carbon dioxide and sunlight.

In conclusion, we can decrease overall atmospheric CO2 by increasing photosynthesis or reducing cellular respiration.
