okay i don't think you meant autoGRAPh but autoTROPH- although the autograph definition is spectacular... an autotroph is basically something that can feed itself (or possibly live all on it's own) an example: plants- they make their own food from photosynthesis and cellular respiration. us humans are not an example of an autotroph; we are heterotrophs- we depend on other things for food or we don't make our own food.
An autograph is a signature. If someone asks for your autograph they want you to sign your name on something (a piece of paper, Baseball uniform etc.).
