<P> Parasitic nutrition is a mode of heterotrophic nutrition where a parasitic organism lives on the body surface or inside the body of another type of organism ( a host ) and gets nutrition directly from the body of the host . Since these parasites derive nourishment from their host , this symbiotic interaction is often harmful to the host . Parasites depend on their host for survival , since the host provides nutrition and protection . As a result of this dependence , parasites have considerable modifications to optimise parasitic nutrition and therefore their survival . </P>
