How do humans use air?
Air is pulled into the body by lungs and used to fill tiny air sacs that allow blood cells to pick up oxygen, which is then distributed across the body’s cells. Through the process of cellular respiration, this oxygen can then be used to break down sugars and create energy.
Why do we need air answer?
Living things need oxygen to survive because we can’t survive without oxygen. It is vital that living things respire to get the oxygen for living cells to function. Without air, there is no life. Plants use Carbon Dioxide (together with sunlight and water) to produce energy and give out Oxygen as a by-product.
