Energy is defined as the ability to do work. Cellular respiration provides energy for living organisms. So, cellular respiration is important because it provides the energy for living organisms to perform all of the other necessary functions to maintain life.
Cellular respiration is a chemical reaction that allows cells to convert food energy into chemical energy. All organisms perform some form of cellular respiration, because without the correct form of chemical energy, cells can't perform work to sustain life.
