Understanding Parasites and Their Effects

The video tutorial explores how parasites manipulate their hosts for survival, using a cause and effect text structure. It focuses on analyzing the actions of parasites, such as the crustacean Simothwa exagua, and their effects on hosts. The lesson guides viewers through steps to identify actions, their effects on hosts, and impacts on parasites, using a cause and effect organizer. The tutorial concludes by summarizing how parasites use hosts for sustenance, protection, and transportation.
