Answer:
All of the cherries on her tree were eaten by the crow.
Explanation:
When using passive voice, the receiver of the action typically goes first and then the doer of the action is after it, as opposed to active voice when the doer of the action is first and then the receiver is afterwards. So, the receiver of the action is the cherries on the tree and the doer, or the thing that ate the cherries, is the crow.
