Nitrogen Cycle
Like hydorgen, nitrogen, and carbon, oxygen is a basic element of life. It is colorless, highly reactive and said to have come from the vapor of water. It turns into bluish liquid at a temperature of -183° C. Oxygen plays a vital role in life. Here are some ways that oxygen is needed:

(This
figure shows a very broad overview of oxygen cycling in nature.)
- It is obviously needed for breathing!!!!
- It is needed for the decompostion of organic wastes,
- Water can dissolve oxygen and it is this dissolved
oxygen that supports aquatic life.
- Oxygen is used during the process of creating energy in living cells.
What produces oxygen?
- Oxygen is created by plants and used by animals.
- Plants use
the energy of sunlight to convert to carbon dioxide and water into carbohydrates and oxygen in a
process called photosynthesis.
- Animals
form the other half of the oxygen cycle. We breathe in oxygen
which we use to break carbohydrates down into energy in a process
called respiration.
- Above the state of Texas alone rests over one trillion tons of it.
- Like water not all air is usable to you.
- Even with all of this volume, air must constantly be reused.

Did you know that the air you are
breathing now was in someone else's lungs earlier.
Air is the ultimate recyclable material!!!
