Geothermal energy is only produced in the western (generally) part of the US. The Southeast and New England areas barely use geothermal energy. It all depends on how much potential a certain area has for certain forms of conducting electricity.
Well I don't know much but I do know that they are different because unicellular can self produce which means they can reproduce without someone else but multicelluar needs someone else to reproduce
It might have animals that depend on this "animal" for a food source. If we were to remove it, all the animals that are after this "animal" on the food chain will die out and the animals that they eat will over populate.
