Final answer:
Parasites typically do not immediately impact the survival of the prey population, as it is beneficial for the parasite to allow the host to live longer to complete its reproductive cycle. The correct answer is C. Survival.
Step-by-step explanation:
Parasites do not have an immediate effect on the survival of the prey population. The correct answer to the question is C. Survival. While parasites depend on their hosts for nutrients, they generally do not immediately kill their hosts.
This is because it is advantageous for the parasite to keep the host alive for an extended period to complete its own reproductive cycle before moving to another host. Therefore, a parasite's impact on the immediate survival of a prey population is not typically observed.
