उत्तर
Adaptations evolved in parasites for their parasitic mode of life:
1. Excessive multiplication: Parasites multiply excessively to produce a large number of young ones so that some of them may survive in the unfavourable conditions and reach the host.
2. Anaerobic respiration: Many endoparasites may respire anaerobically.
3. Adhesive organs: Parasites have adhesive organs to prevent dislodging from the host-like suckers in leeches and tapeworms.
4. Resistant cysts and eggs: Resistant cysts and eggs help in the safe transfer of parasites to their specific hosts.
