विकल्प

One organism is benefited, other is affected.
उत्तर
One organism is benefited, other is affected.
Explanation:
Parasitism is an interaction between two species in which one species (parasite) derives benefit while the other species (host) is harmed. For example, lice (parasites) on the human body and ticks on dogs represent this interaction, where the parasites receive benefits (as they derive nourishment by feeding on the blood of humans). On the other hand, these parasites reduce host fitness and harm the human body.
