  1. Oxygen Cycle By: Will, Miles, Daniel, And Bob

  2. Path of Movement

  3. Importance • Plants are the main source of breathable oxygen for all animals that depend on it. • During photosynthesis plants absorb carbon dioxide and release oxygen.

  4. Resivoirs • 99.5% of all oxygen is located in the crust and mantle of the earth. • .36% of the earth’s oxygen is in the atmosphere which is the oxygen we breathe. • Although oxygen is the most abundant element on the planet we can only use a small portion of it.

  5. Chemical Formulas • The chemical formula in photosynthesis is 6CO2 + 6H2O + energy → C6H12O6 + 6O2. • The chemical formula in chemical weathering for oxidized iron rocks is 4FeO + O2 → 2Fe2O3. • These are the most important chemical formulas having to do with oxygen.

  6. Human Impact • Humans along with every other animal completely depend on oxygen to make possible chemical reactions in their body's. • The worst thing humans can do is to destroy forests which they are doing. • Without any plants or forests the oxygen cycle will cease to occur killing all humans.
