Explanation:
Let me add the disclaimer that I'm not a native English speaker, but I want to help. :)
There are essential and nonessential clauses: they're differentiated by commas, like in this example: "<em>Carrots and brussel sprouts, which are often discarded, happen to provide many nutrients". </em>This is an example of a nonessential clause since it utilizes a comma to deliver more information.
Here are a few more examples you can use to compare the answers/future questions with:
<em>"The man who forgot his wallet is coming back to retrieve it."</em>
<em>"Katie, who has the same class as Henry, is my best friend."</em>
<em>"I like dogs that have sleek fur."</em>

The prepositional phrase is "on a high shelf" since ON is a preposition.
