With less oxygen there is less carbon dioxide being produced for the plants so photosynthesis decreases.
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP)
If you compare them, Denver has a much colder climate.
