Explain Parasitism and co evolution with the help of one example of each.
Parasitism: It is a mode of interaction between two species in which one species that si parasite, depends on the other species that is the host for food and shelter. In this one organism is benefitted, the other one is harmed.
For e.g- Human liver fluke, Malarial parasite, Cuscuta
Co-evolution: It is the relationship between two interacting organisms where both organisms failed to survive in the absence of the other one.
For e.g: Fig and fig wasp, Ophrys and bumblebee, etc.
