The parasite derives it's nutnent and sometimes shelters from the host while the host is harmed. Saproohygtism is a mode of deeding in which fungi or some soil bacteria derive food from the decaying organic matter (dead plants and animals )Commercialism is an association between two organisms of different species in which one organism (commensal) benefits while the other one is not harmed eg. shark and jemora fish; epiphyte and a large tree such as palm tree. Symbiosis used in this context is mutualism which is an association between two organisms of different species  which both benefits eg. lichen, rnycorrhiza etc.
