Bio Notes 11.14 Parasites and pathogens have much in common. They: A) Are both symbiotas characterized by positive effects on their hosts B) Both demonstrate that symbioses are tremendous generators of diversity C) Are both parts of symbioses that can have large effects on the communities of their hosts D) Are heterotrophs that are k-selected relative to their hosts E) Are autotrophs that are r-selected relative to their hosts My Answer: C Answer: C Communities are collections of organisms living in one area (collection of populations) Know the opening of ch. 34 (larvae and wasp parasitism example) Competition is one of the principal factors that can influence community composition Barnacles (Chthamalus and Balanus) Chthamalus is forced up rocks because balanus is lower and wants less sun By invoking the competitive exclusion principle we can come to understand the diverse assemblage of species in communities How does this sort of competition differ from the sort that Darwin posited acting in the struggle for existence?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
