Today's riddle is split into two. Find out what I am.
P.S. This riddle works much better when told aloud, so some spelling has been adjusted to how you would hear it, and it is not necessarily the word that is actually there.
I am needed to break bread,
No edge used for me to spread.
To dance through the forest with song and grace,
Ever to become a tasty snack that once had a face.
Regarded as the primary, the protag, or the first,
Now as the crown of a beast, who hungers and thirsts.
Even some people, are considered to have me,
To clarify that which is most important you see.
