(a)
To determine: The type of relationship between the host and a parasite is parasitic or mutualistic.
Introduction: Parasite is an organism which lives on the surface or inside the body of another organism. It derives nutrition from the host for their survival and daily requirements. Sometimes, the
(b)
To determine: The route of evolutionary change.
Introduction: Parasite is an organism which lives on the surface or inside the body of another organism. It derives nutrition from the host for their survival and daily requirements. Sometimes, the parasites and host represent a mutual or symbiotic relationship. In symbiotic relationship, both the species are benefitted by the product of an individual species.
(c)
To determine: The evolutionary change in host, symbiont, or both during the change from one interaction to another.
