Exploiter-Victim Relationships

Exploiter-Victim Relationships. Host-Parasite: Host death need not occur, and often does not; birth rate of host reduced by parasite Host-Parasitoid: Host death always occurs Predator-Prey: Death rate of prey increased by predators Herbivore-Plant: May resemble predation or parasitism.

Population Interactions

Population Interactions. Competition for Resources: Exploitative competition : Both organisms competing for the same resource(s); e.g. nutrients, light, prey. Interference competition (amensalism): Organism exert direct, negative effects on another (allelochemical and allelopathy)
