Question

People breathe oxygen every day. Oxygen is one of many gases found in the air. It is an essential gas that animals need in order to survive. The cells inside animal bodies use oxygen for energy. As we breathe in, oxygen enters our bodies, and as we breathe out, carbon dioxide leaves our bodies. Carbon dioxide is another gas that is in the air we breathe. Normally, breathing a lot of carbon dioxide can be poisonous, but since it is mixed with many different gases in the air, it is safe to breathe.

So where does the oxygen in the air keep coming from if animals are breathing it all in? Plants. Plants use their leaves to take in carbon dioxide from the air and use it to make their food. Then, plants release gases back into the air. Oxygen is one of the gases. The oxygen they give off balances the air that we breathe.
