In English grammar, "what" is used to ask about things or ideas, while "whom" is used to ask about people or objects that are the object of a verb or preposition. "What" is used for subjects and direct objects, while "whom" is used for indirect objects and objects of prepositions. For example, "What are you reading?" asks about the thing being read, while "Whom did you give the book to?" asks about the person receiving the book.
An indirect object is a noun or pronoun that follows an action verb, receives the direct object, and answers: To whom and To what.
"What" is a pronoun. It's the object form of "who", meaning that's used after prepostions ("to whom, by whom") and in formal speech as the direct object of verbs (whom should I tell?) "What" can be a pronoun, adjective, or adverb. In "What did you say?" it's a pronoun. In "what books have you read?" it's an adjective. In "what with one thing and another, this is hard" it's an adverb.
Food is the direct object. This sentence does not have an indirect object. The D.O. answers the question "the dog ate what?" An indirect object would answer the question "for whom / to whom / for what?" as in "I gave the dog a bone." I gave what? A bone (D.O.) I gave the bone to whom? The dog (I.O.)
D.O. is what or whom I.O. is to whom or for whom

The indirect object in a sentence tells to whom or for whom the action is being done. It usually answers the question "to whom" or "for whom." For example, in the sentence "I gave her a book," "her" is the indirect object indicating to whom the action of giving is done.
The accusative case answers the question "whom?" or "what?" in relation to the direct object of a sentence. The genitive case answers the question "whose?" or "of whom?" to show possession or relationship between nouns.
