Answer:
Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.Oxygen was first isolated by Carl Scheele, officially discovered by Joseph Priestly (because he published first), and named by Antoine Lavoisier. ... Thus, in addition to being essential to life (certain bacteria are exceptions), oxygen had a significant role in the development of modern chemistry.
