Final answer:
Parasites use mind control to manipulate their host's behavior for their own benefit, ensuring their own survival and reproductive success.
Step-by-step explanation:
Parasites use mind control to manipulate their host's behavior for their own benefit. In parasitism, the parasite benefits while the organism being fed upon, the host, is harmed. The host is usually weakened by the parasite as it siphons resources the host would normally use to maintain itself. By controlling the host's behavior, parasites can ensure their own survival and reproductive success.
