Well, just like in most parts of the world, the plants usually get nutrients from the soil and water?

What I want to know is how 15 species lived down there for 5 millions years and also exist in the outside world just the same.

How does THAT work?

I wonder just how "isolated" the cave was? They make it sound like it was an air-tight, sealed pocket of stuff living down there. But there was a water flow. So it obviously was not THAT isolated...

its some anaerobic bacteria (gets energy from decomposing CO2, like plants, but instead of light (photosynthesis) it uses a chemical reaction (sulphuric, i believe) chemosynthesis, and some more microorganisms that metabolize methane.

They form a paper-like foam on the surface of the water (which comes from below the cave, cave is essentially flooded). Such lifeforms are autotrophs, and they are the plant equivalent of that ecosystem. The lowest member of the food chain (in this case, herbivore equivalent) are the creepy crawlies that feed off the above-mentioned foam.

The only part that is unclear to me is that there is a first observed, unique type of leech there. What does it leech off of, if there are only arthropods down in that cave?

i know, i read about that cave and dabbed in biology, just saying for coletheuber
also, leeches don't really survive off blood, they can also swallow whole small creepy crawlies

They're probably scavengers, and eat leftovers or the dead of the other species.

what i meant is that there are bacteria that produce organic compounds without sunlight like plants, chemosynthesis instead of photosynthesis, basically what latentvirtue said, and it's pretty rare and interesting to find an ecosystem that works without sunlight and is so big

oh,don't take me with "i want to save everybody"
It's a job like any other job.
Study,be good at what you do and you will make money.By being good at what you do you help people too and you help yourself.
90% of my colleagues are here because they too have no ideea what to do.
If i learned something it's that doctors are people with SLIGHTLY over average intelligence,superiority complexes that hide their fragility.
We have the highest suicide rates in any job,and it prevails in the years one and two of medschool.This profession crushes your dreams and expectations very soon.You become bitter.

that's exactly the reason why you should aspire for more that just a job, so you don't become a bitter husk of a person who eventually kills themselves
