In Science Class, our previous subject was entitled, Symbiosis. This is a relationship about two species that work together. The results of the relationship could end up either hurt one or both, or, benefiting on or both. In Symbiosis, there are three possible categories that they would fall under, Parasitism, Commensalism, or Mutualism. Parasitism is when both of the species in the relationship are harmed. An example would be the Shelf Fungus and the Hickory Tree because they both aren't getting anything out of the realtionship but instead are being harmed. The next one, Commensalism, would be when one of the species is benfited but the other on isn't harmed either. An example would be a bird living on a tree because the bird is getting shelter while the tree isn't getting harmed. type is Mutualism, this is when the two species are both getting benfited. An example would be a bee and a flower because they both are helping each other to get an important element needed in there lives. As I was doing a litter more research on Symbiosis I found out that the word comes from the greek origin, because syn means with and biosis means living. I also learned that Heinrich Anton de Bary, a German mycologist, gave Symbiois the definition of: "the living together of unlike organisms". I cant wait to learn more about this topic!
