1. PARASITISM  Parasitism is a species interaction that resembles predation in that one individual is harmed while the other benefits.  However, in parasitism, the parasite feeds on the host individual.  This does not result in the immediate death of the host. Rather, the parasite may feed on the host for a long time instead of killing it. Adrienne Farmers
