Explanation:
Proglottids are segments in cestodes that contain bot the male and female reproductive organs. These segments go ahead to make eggs and then dettach form the worm. They are excreted and become agents of infection on the next hoist. Proglittids formed near the neck of the worm are immature while those at the tail end are literally bags of mature eggs.
The scolex is the head of the worm that is attached to the host. It is also the part that ‘sucks’ nutrients from the host. It has hooks that it uses to anchor itself in the host. In some species, rather than hooks, there are suction-cups that use suction for anchorage.

Answer:
D. predator population will decrease
Explanation:
If the population of prey species decreases then the competition between the predator population will increase and natural selection will act on them. So nature will select those individuals among predators who are more fit and adapted and less fit individuals will die.
So a few year after the predator population will decrease as there are not enough prey to support the large population of predators which was present when prey were abundant. Therefore the correct answer is D.
