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)?

Your stomach/intestines are lined with muscles that contract and expand to “churn” and move the contents along, so when you eat the food dampens the sounds.
And when you’ve not eaten anything in a while they are just churning air and digestive fluids in an empty bag. So as it’s pushing more air than food you get bubbles forming and those getting pushed through through your digestive system is what causes the “growling” sound.
