Question about Dragon City Game about the Dragon City Guide Website --

When You choose a dragon to see it's category, earnings, etc.-- some dragons (not all) have a "difficulty" rating -- what exactly does this mean?? Example Poo dragon is difficulty 1 - Flame is 2 -- Alpine is 3 and then some have no rating ??? I really don't know and can't seem to find explanations on the website. Anyone know??
