a parasite is an oragnism that lives off another organism to the host's detriment, a saprophyte is an organism that lives off dead things and mutualistic I assume is similar to symbiotic where two organisms live off each other with mutal benefit. Now examples: ringworm is a parasitic fungus Microsporum, Penicillium sp are saprophytes (live off of dead plants) and mycorrhiza are fungi that live in plants and fix nitrogen for them.
