Read the following statements and choose the correct option: 1. The human liver fluke depends on two intermediate hosts to complete its life cycle 2. Most of the parasites are host friendly 3. Majority of the parasites harm the host; they may reduce the survival, growth and reproduction of the host and reduce its population density. 4.

Step-by-step solution

Many parasites have evolved to be host-specific (they can parasitise only a single species of host) in such a way that both host and the parasite tend to co-evolve. The human liver fluke depends on two intermediate hosts to complete its life cycle. Majority of the parasites harm the host, they may reduce the survival, growth and reproduction of the host and reduce its population density. Majority of the parasites harm the host; they may reduce the survival, growth and reproduction of the host and reduce its populat
