           | biofilm produced by sulfur-eating bacteria, which in turn
           | metabolize sulfur from the sulfur-rich stream in the cave.
           | 
           | So the whole food-chain here is: sulfur -> bacteria -> midges
           | -> spiders.

             | 
             | This is a hugely erroneous claim that is much too
             | frequently encountered in the popular publications.
             | 
             | Both in this cave and in hydrothermal vents, most
             | autotrophic bacteria use free oxygen to oxidize the
             | hydrogen sulfide, producing thus the energy needed for
             | autotrophy.
             | 
             | The free oxygen comes from the phototrophic algae and
             | plants (located elsewhere), i.e. from solar energy.
             | 
             | On Earth, there are only 2 kinds of autotrophic bacteria
             | and archaea that may be independent from solar energy, the
             | acetogenic bacteria and archaea and the methanogenic
             | archaea. Both kinds obtain energy from free hydrogen and
             | carbon dioxide, the former producing acetic acid and the
             | latter producing methane.
             | 
             | These 2 kinds of bacteria and archaea need free hydrogen
             | and most of them are killed by free oxygen. Sometimes the
             | free hydrogen is produced by fermentation of organic
             | substances, like in our intestines, so also coming from
             | solar energy, but free hydrogen is also produced by the
             | oxidation of volcanic rocks by water, when its origin is
             | independent of solar energy and dependent only on the
             | internal heat of the Earth, which produces volcanic rocks
             | that are in chemical equilibrium at high temperatures deep
             | inside the Earth's mantle, but they are no longer in
             | chemical equilibrium after reaching the cold surface of the
             | Earth.
             | 
             | Thus deep underground or in certain places on the bottom of
             | the oceans, where free dihydrogen is abundant and there
             | exists no free dioxygen, there are communities of
             | acetogenic and methanogenic bacteria and archaea that are
             | independent of solar energy, but this is not the case for
             | this cave and for many of the hydrothermal vents, where
             | both hydrogen sulfide and free dioxygen are abundant, so
             | aerobic bacteria are dominant.
             | 
             | Anywhere where there is either air or water with dissolved
             | dioxygen, the living beings use the most efficient energy
             | source, i.e. the oxidation of either organic or anorganic
             | substances with the free dioxygen, so they depend on solar
             | energy, even when there is no light in that place.

       | felt feverish and disoriented. The wounds on my calf had become
       | inflamed. The cold in the apartment added to my discomfort.
       | 
       | The next few days were a blur. I missed work and the few social
       | engagements I had planned. Eventually the wounds began to heal
       | but I was still bone cold and the light from windows hurt my
       | eyes. Winter has set in and the plastic I'd applied to the
       | windows had detached from the wind allowing icy drafts into the
       | apartment. I diligently applied another layer of plastic on the
       | windows, this time using packing tape to secure the corners!
       | 
       | It was a harsh winter and I repeated this process several times
       | until the windows were opaque and along with the shades allowing
       | very little light through.
       | 
       | One day as I sat in the dark slowly eating my meal there was a
       | knock on the door. It was my close friend from work wondering
       | what had happened to me. I must have been a sight judging from
       | his startled appearance.
       | 
       | Summer came and I emerged occasionally to acquire food and other
       | necessities only to scurry back home when the outside became too
       | overwhelming. I eventually found remote work, and here I am today
       | in my cold dark apartment with high ceilings and drafty windows.
       | 
       | Note if you made it to the end, thanks for indulging me. This is
       | based on a real apartment, windows and spiders!
