How is a parasitic relationship different from a mutual or commensalistic relationship?
A symbiotic relationship is a relationship in which the two things are mutually dependant on eachother. A parasitic relationship is a relationship in which one thing (usually smaller than the other) is mutually dependant on the other. But the parasite is doing this at the other things cost. For example: A coral reef and a type of coral called Zooxanthellae have a symbiotic relationship with eachother. One reason the Great Barrier Reef is dying is because of the bleaching (loss of colour, which is not good) of Zooxanthellae. There are many examples of parasites, such as mosquitoes. An excellent example of a parasite is the leech. When the come in contact with your skin, they start sucking the blood out of you. This is why some hospitals and clinics use them to suck out poison. But after the poison is gone they keep sucking, like they do normally, which can be harmful.
