Explanation:
Inhaled air consists of 78% nitrogen gas, 21% oxygen gas, 0.0314% carbon dioxide gas, and water vapor.
Exhaled air consists of 78% nitrogen gas, 16% oxygen gas, 4% carbon dioxide gas, and water vapor.
The decrease in oxygen gas is due to aerobic respiration, which requires oxygen gas for the electron transport chain.
The increase in carbon dioxide is also due to aerobic respiration, which produces carbon dioxide as a waste product.
Overall chemical equation for aerobic respiration:
