Detailed explanation-1: -The correct option is A True. Respiration in animals: The percentage of CO2 in inhaled air is 0.04% whereas in exhaled air it is 4.4%. Therefore, we can say that exhaled air has more percentage of carbon dioxide than in the inhaled air.
Detailed explanation-2: -Answer: The exhaled air contains more carbon dioxide because the carbon dioxide produced during respiration is removed out of the body as the exhaled air during the process of respiration.
Detailed explanation-3: -The amount of inhaled air contains 21% oxygen and 0.04% carbon dioxide, while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide. This is because our cells use oxygen from the inhaled air to release energy and give out carbon dioxide and water vapour.
Detailed explanation-4: -Exhaled air contains less oxygen and less carbon dioxide than inhaled air. No worries!
