What's the term for an organism that lives on or in another ?
Parasitism is not strictly correct. Parasitism is a subcategory of symbiosis (the participants are symbiotes). Symbiosis refers to a close association between two diffrent organisms. Parasitism is a relationship in which one species benefits while the other is harmed. There are forms of symbiosis in which both species benefit or in which one benefits or is harmed without the other being affected or that is harmful to both species (mutualism, commensalism, amenalism, respectively and I cannot remember the term for both being harmed). These are not stricly speaking parasites, but are still symbiotes and live in close association. Symbiosis can be further devided into ectosymbiosis (one participant lives on the other; this includes within the digestive tract as it is technically outside your body) and endosymbiosis, in which one participant lives within the tissues of the other.
A tapeworm would be a parasite (benefit for it, harmful to you) that is an ectosymbiote (lives in the intestine). Plasmodium falciparum (cause of malaria) would be a parasite (benefit for it, harmful to you) that is an endosymbiote (lives in the tissues/blood). Your gut flora that help in digestion are generally mutualists. We benefit from their presence (except when they cause gas) and they benefit by being there.
Parasitism if the organism harms the host.
Commensalism if the host isn't harmed but doesn't benefit.
