Activity 49.1 Life Cycle of the Malaria Parasite

CDA49_1.jpg A parasitism is a species interaction in which one organism derives all or most of its resources from a living host, essentially exploiting that host as a habitat. Hosts and parasites have evolved in concert. Hosts evolve strategies to minimize the cost of parasitism, and parasites evolve strategies to receive more resources from the host. In this activity, you’ll see the interactions among humans, mosquitoes, and Plasmodium—the parasite that causes malaria. This is an excellent example of how multiple species can be tied together in complex ecological interactions.
