What job is the noun clause doing in this sentence- A polite guest will eat whatever served?

In the sentence "A polite guest will eat whatever is served", the noun clause "whatever is served" acts as the direct object of the verb "eat".

Here's why:

* Noun clauses function as nouns. They can act as the subject, object, or complement of a sentence.

* In this sentence, the verb "eat" requires a direct object to complete its meaning. The object answers the question "What does the guest eat?" The noun clause "whatever is served" provides the answer.
