Final answer:
Exhaling contributes to the concentration of carbon dioxide in the air.
Step-by-step explanation:
False. When you exhale, you are actually releasing carbon dioxide into the atmosphere, making the concentration of carbon dioxide higher in the air. When we inhale, we take in oxygen and exhale carbon dioxide as a waste product of cellular respiration. This process occurs in our lungs and is essential for maintaining the balance of gases in our body.
