I'm building an ecology that revolves around an infinite food source being eaten by Trolls, who then make more Trolls, which they then kick out of the cave because they don't fit around the food source.
So outside of the cave, the main source of food is basically Trolls. (Either the corpses of starved ones, or just the young ones milling about). But some of the other predators in the area cannot do Fire or Acid damage, but are clever enough to knock one down and hunt in groups big enough that they can eat an unconscious Troll in one sitting.
Is there any lore available (either in ecology articles, or D&D stories, or something) on what happens if you eat the whole thing without killing it? Will it just die at some point, or will it regrow in one (or more) of the stomachs it's in?
