Question
Explain Parasitism and co-evolution with the help of one example of each.

Answer

Mode of interaction between two species in which one species (parasite) depends on the other species (host) for food and shelter/one organism is benefitted, the other is harmed.
e.g. Human liver fluke/Malarial parasite/Cuscuta.
Co-evolution is the relationship between two interacting organisms where both organisms failed to survive in the absence of the other.
e.g. Fig and fig wasp/ophrys and bumble bee.
