Which sentence uses correct end punctuation? Evergreen trees retain their green color throughout the winter! Look at that beautiful, red sugar maple tree? Plants stop making chlorophyll in the winter to save energy, o Why do some trees drop their leaves in the autumn and others do not?

The correct end punctuation is "Why do some trees drop their leaves in the autumn and others do not?".

Explanation:

"Evergreen trees retain their green color throughout the winter" is not an exclamation, merely a statement, so it should be finished with a period rather than an explanation point. "Look at that beautiful, red sugar maple tree" is an exclamation, not a question, so it should have an exclamation point rather than a question mark. "Plants stop making chlorophyll in the winter to save energy" should be finished with a period unless there's another part to the sentence. "Why do some leaves drop their trees in the autumn and others do not" is a question, so it is properly finished with a question mark.
