We all know that normally (which means excluding stomach viruses, period cramps, parasites etc.) and mostly our stomach growls when we are hungry.
But
1.) how does it create that sound, by vibration (of some organ?) or something else?
2.) does it mean our stomach has finished processing (digesting) the food, or does it mean they used up all the energy it provides (I don’t think it is possible, since we need it for life…. but does it mean it’s using the last bits of the energy left)?

In the question above yours, u/mnxt said: “The digestive tract has a series a sphincters which open and close involuntarily for normal one-way operation. The anal sphincter is the last of them.”
And I replied with what’s essentially your answer: when your stomach is rumbling, it’s farting internally.
This happens when the stomach is working, as described above, and there’s gas in the mixture. Gas bubbles being squeezed along the intestines make them vibrate. It means that your intestines are actively moving stuff along.
