It should perhaps also be noted that most interrogative pronouns can also function as indefinite pronouns, so ‘what?’ can also mean ‘something’ and ‘where?’ can also mean ‘somewhere’. Since 吗 is only used to turn declarative sentences into questions, adding 吗 to a question that contains an interrogative pronoun will turn the question itself into a declarative sentence, and the interrogative pronoun will be understood as an indefinite pronoun: 你吃什么？ _What will you eat?_ vs. 你吃什么吗？ _Will you have something/anything to eat?_

Yes–no questions in English are called 是非疑问句 in Chinese, but most of the times you don't need to use 是 or 不是 to answer those questions. Eg. A: 你吃饭了吗? B: 还没有呢. You need to use 是 or 不是 to answer those questions that demand your confirmation or denial, and usually those questions contain 是 and/or 不是. Eg. when interrogating a suspect, a policman may ask: 我看你就是杀人凶手吧? The suspect may say: 不是 to deny.

Forgive me for asking, but it looks like you haven't answered the question. The asker wants to know why questions like "你再吃什么？" don't end in 吗?

@xiaohouzi79 That was added by you isn't it? My reading of OP's question is to confirm his understanding in his last statement, which is what this answer is positively acknowledging on.

@NS.X. - His main question had 3 parts: 1. Saying he was unclear why these question don't end in _ma_. 2. Asking if _ma_ was only used for turning a statement into a yes/no question. 3. Asking if _ma_ was used for all questions. These three questions remain unedited. My personal thought was that your answer only partially answered one of his questions which is why I wanted to check my understanding.

@xiaohouzi79 I see your point. I admit this answer isn't very explicit, but I still find all three questions answered. The OP already noticed the difference between questions begin with WHAT and yes-no question and had a theory in place to explain, that is, it (ma) is 'only necessary for turning a declarative statement into a yes/no question' and it is 'not used for all questions of the forms who, what, why, etc'. This answer first confirmed that statement, then recapped it in another way, essentially 'yes, ma is required for yes-no questions but not interrogative questions'. What else?

Your guess is correct. 吗 (ma) is usually used at the end of a narrative sentence, which without 吗 can become a declarative statement.

吗 has other usages but at this learning stage you shouldn't let them distract you.

In general, Chinese interrogative sentences must contain a question word to be a valid question. 吗 is a question word, but doesn't necessarily have to be placed in every question.
你吃饭了吗？ Have you eaten yet? （吗)
你吃了什么？ What have you eaten? (什么)
你在哪里吃了早餐？ Where did you eat breakfast? (哪里)
你怎么还没吃饭？ How have you not eaten yet? (怎么)
你为什么要吃那个? Why do you want to eat that? （为什么)
