ELI5: How does a queen ant come to be?

From what I understand, queen ants are usually much larger than other ants in their colonies and they pretty much just sit there and wait for others to bring them food. However what I don't understand is how does an ant become a queen ant? Are some ants just born much bigger than others and they automatically become queen ants? If so, why are those certain ants born much bigger than others? Or are queen ants born normal and somehow become larger than others during their lifetime and then become queen ants? It's a massive mystery to me! 

Also, I guess same question applies to other species that has similar things to queen ants, like bees, etc. 

Please shed some light to me on this! :)

It varies widely by species of ants, but most feed a few larva some special jelly and those larva will grow to become queen.  Sometimes they'll make too many queens and the new queens have to fight to the death.  Some ants will "promote" one sterile female, usually decided by fighting, into their new queen.  In some species, the queen makes the decision whether to make another queen or not.  Some ants don't have queens.  Some Ants have lots of queens.  

Ants are interesting.
