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: "Carrots and brussel sprouts, which are often discarded, happen to provide many nutrients". 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:
"The man who forgot his wallet is coming back to retrieve it."
"Katie, who has the same class as Henry, is my best friend."
"I like dogs that have sleek fur."
Really hoped this was useful!
