what is the difference between breathing and respiation?

Both breathing and respiration are required for all living organisms. Generally, breathing and respiration are often considered the same; however there is a big difference in the meaning of the two. 

Breathing is when you consistently breathing air in and out. It is the process of taking in oxygen and expelling carbon dioxide. 

Respiration is a process in which the C-H bonds ( carbon-hydrogen bonds) in food are broken down by oxidation reduction reactions and the energy is transformed in to ATP
