Answer:
•Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration  puts it back.
Explanation:
Photosynthesis:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Carbon dioxide + water + energy →   glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.
Cellular respiration:
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
In this way it release the carbon dioxide back into atmosphere.
