The thing that makes me sway towards deep-sea vents is that they actually have producers in the form of chemosynthetic bacteria that can use the sulfur and iron for energy. It actually gets pretty extreme: [Giant tube worm - Wikipedia, the free encyclopedia](Riftia - Wikipedia)

Benthic would be a good answer, though. I’ll read more about it.

edit: it appears that the benthic zone is at the bottom of anything. So the benthic zone of a shallow lake would still depend on photosynthesis and sunlight. I guess that makes the deep-sea vents the best answer?
