Oxygen is necessary for breathing. All the living things use the oxygen for respiration. During respiration, oxygen breaks down food to give carbon dioxide, water and energy.
Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow.
