Respiration
Cells can release energy in two basic processes: Cellular respiration and fermentation. Cellular respiration requires oxygen but fermentation does not. Cellular respiration releases MUCH more usable energy then fermentation does.
That's not a full question, but I think I know what you are asking. Aerobic respiration > anaerobic respiration > fermentation.
A cell releases energy from food in the process of cellular respiration which is in the presence of oxygen, or fermentation which is in the absence of oxygen.

Fermentation!!!!!
Adenosine triphosphate (ATP) is a common product in both cellular respiration and fermentation. ATP is the energy currency of the cell and is produced during these processes to provide energy for cellular activities.
cellular respiration
Effective cellular respiration releases a large amount of energy (ATP). In order for effective cellular respiration to occur, oxygen must be present in the second stage of cellular respiration, the Krebs Cycle. If after the first stage of cellular respiration, glycolysis, there is no oxygen present, then ineffective cellular respiration occurs and the process is carried out by fermentation. Fermentation is an anaerobic process that results in the formation of ethyl alcohol or lactic acid and the cycle produces a net ATP gain of 2, whereas the net ATP gain of effective cellular respiration is 36 ATP molecules. Therefore cellular respiration in the presence of oxygen deals out a large amount of energy, but if not in the presence of oxygen, it deals out a small amount of energy.
Fermentation and cellular respiration are similar in that they both involve the breakdown of molecules to produce energy for cells. However, fermentation does not require oxygen, while cellular respiration does. Both processes also produce waste products, such as lactic acid in fermentation and carbon dioxide in cellular respiration.
The process organisms can get energy from besides cellular respiration is fermentation. This does not result in nearly as much energy, and releases lactic acid rather than carbon dioxide and water. This means that it is less efficient, but it does not require oxygen.
Cellular respiration is the process that releases energy by converting oxygen and glucose into carbon dioxide and water. This process occurs in the mitochondria of cells and produces ATP, which is the main source of energy for cellular activities.
They both are similar in releasing energy.In cellular respiration food is broken down to cell level and a lot of energy is produced and similarly in fermentation it is described that it is the process of getting energy from oxidation of organic compounds.
