Okay, so 'quack-quack' isn't a real scientific term, but it's what little kids say ducks say! ðĶ It's onomatopoeia, meaning it sounds like the sound it describes. Think of it like 'meow' for a cat or 'woof' for a dog. It's a simple way to mimic a duck's call. But remember, ducks have a whole range of vocalizations, not just 'quack-quack'! They can whistle, grunt, and even coo. So, while cute, it's a super basic, kinda childish representation.
