Correct the sentence so that it is grammatically correct: My mother went outside to feed the ducks there breakfast, but when she went to grab the food bowl she noticed it were empty.
There should be changed to their. This shows possession of the breakfast; it belongs to the ducks. Were should be changed to was. The food bowl is singular, so was is the appropriate form to use. If it were food bowls, then the plural word bowls would be followed by were.

What is wrong with the following sentence: The girl is going to the supermarket to get some flowers yesterday.
The verb 'is going' is in the wrong tense. Since the subject performed the activity yesterday, the verb should be in the past tense. Therefore the sentence should read: The girl went to the supermarket to get some flowers yesterday.
