Is it true that air breathed out contains more carbon dioxide than air breathed in?

Yes. When you breath, you take in oxygen and breathe out CO2. According to Wiki Answers (see link), an exhaled breath is about 4% CO2. Atmospheric CO2 is between 300 and 400 ppm, or 0.03% to 0.04%.


Why is there a higher percentage of CO2 in the air exhaled than inhaled?

The air we inhale comes from the athmosphere; the percentage of CO2 in the athmosphere is next to insignificant. The air we exhale comes from the cellular environment; cells give off CO2 as part of their metabolism, thus CO2 venous blood concentration is high
