Definition: Thermits, also known as "thermals" or "thermophores," are a group of microorganisms that inhabit the surface of rocks and minerals. These organisms produce heat through the process of photosynthesis, which is the conversion of sunlight into chemical energy, primarily in the form of glucose. The term "thermits" comes from their characteristic ability to change color or intensity based on the temperature of the surroundings, as well as their role in forming a layer of mineral coatings
