Which one of the following is not a parasitic adaptation? [Kar. 2013] (a) Loss of unnecessary sense organs (b) Development of adhesive organs (c) Loss of digestive organs (d) Loss of reproductive capacity
Option D. If an organism is living as a parasite it must have adhesive organs for its attachment to the host. Digestive system is not needed since they can absorb the nutrients directly through their skin. there is no need of sense organs as they are completely dependent on the host and everything is available. But they must have a high reproductive ability since there are chances that everyone won't survive.
