Question

Which adaptation of parasite has evolved to sustain their life in host body?

• A. Loss of unnecessary sense organ
• B. Presence of adhesive organ or suckers to cling at the host
• C. Loss of digestive system
• D. All the above

Answer 1

The correct option is D All the above

If an organism is living as a parasite it must have adhesive organs or suckers 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.
