Carbon dioxide is a waste product of respiration and in the lungs it passes out of the blood and is breathed out. Respiration is a chemical process when glucose or other sugars react with oxygen to produce energy. It produces carbon dioxide and water as waste products.

Explanation:

Respiration is a chemical change as new substances like carbon dioxide and water are formed. Also there is change in the mass as glucose is oxidised by oxygen and heat is released. This change is permanent. All these factors conclude that respiration is a chemical change.
