You ever wonder how dwarves... live? I mean those really stereotypical fantasy dwarves that Mine For Gold and Live In Large Underground Cities. How do they get food? Do they have a really trade dependent economy wherein they get food from nearby aboveground cities? The problem with that is that if you anger any of the aboveground cities, they’ll refuse to give you food, and then what you have is no food. This is my attempted solution to this problem, for fun, profit, and because I’m currently writing a story that takes place entirely underground and I’m the kind of writer who needs to know how every single character is getting fed. These “plants” look like normal plants, but are actually an example of convergent evolution. Whereas normal plants get energy from the sun via their leaves, these plants get energy from the ground via their roots. Specifically, chemicals within the ground that they use in reactions that create energy. Yes, I just created a plant that runs on fossil fuels. No, I don’t have regrets (well, I don’t have regrets with regard to creating this plant anyways). Why are there leaves? To cool it down. You see, anything that makes energy makes heat, as per the laws of thermodynamics. Whereas normal plants get their energy aboveground and can therefore just deal with the heat by sitting in the wind and all that, these plants are only roots, and live in caves where air tends to be more stagnant, meaning they’d get real hot real fast. Now let me tell you about ears. If you want to stay warm, cover them. They have a huge influence over body temperature. Why? Because they’re very thin, so when blood goes through them, it’s not insulated from the outside air, and therefore can cool off very fast, go into the rest of your body, and cool that off too. These cave plants do that deliberately through their leaves to vent off excess heat from their energy gathering, and have created leaflike structures to maximize surface area. Tada! Magic (science) cave plants!
