👉 Protarsal is a scientific term that refers to an organism that is capable of living in environments where there are no plants or animals. It was first described by Carl Linnaeus, a Swedish naturalist and botanist, in his 1753 work "Systema Naturae". Protarsals were originally classified as fungi but have since been reclassified as bacteria due to their ability to convert sunlight into chemical energy through photosynthesis.
