Flies eat decaying matter, they also lay their eggs in decaying matter and they also in turn feed off the decaying matter.  They are usually the first step in turning the dead and decaying matter back into soil or continuing the "circle of life".  They also spread diseases or bacteria, which you can also think of as a a life form or you can look at them spreading dieseases and bacteria to the weaker animals or humans.  This way the fly can be looked at as contributing to the "survival of the fittest".
