Can my 16 claim herself as a dependent? if not ,can i claim her earned income on my taxes?

two part question.

1. my daughter wants to file her own taxes this year.  she made about $6000 as a waitress.  I pay all of her living expenses.  is she required to put that she CAN be claimed as a dependent?  what happens if she doesnt?  could she get in trouble since she CAN be claimed?

 

2. in the event that she cant claim herself as a dependent, can i use her earned income as my own earned income since I would get more money back than her and I could give her money from that?
