  • What is true about both predation and parasitism?
    Both involve one organism benefiting at the expense of another.
  • In which type of symbiosis is one organism harmed while the partner benefits?
    Parasitism is a type of symbiosis where one organism benefits while the other is harmed.
  • What is an example of a parasitic relationship?
    A tick feeding on a deer.
  • Which type of relationship is harmful to one organism and beneficial to the other?
    Parasitism is a relationship that is harmful to one organism and beneficial to the other.
  • Parasitism could be considered a form of which of these types of relationships? A) Mutualism B) Commensalism C) Exploitation D) Competition
    C) Exploitation
  • Which describes a relationship in which one organism kills and eats another organism?
    Predation describes a relationship where one organism kills and eats another organism.
  • Ticks feeding off deer and its nutrients is an example of which type of symbiosis?
    Ticks feeding off deer is an example of parasitism.
  • What is the main difference between ectoparasites and endoparasites?
    Ectoparasites live on the outside of the host, while endoparasites live inside the host.
  • How do parasitoids differ from typical parasites?
    Parasitoids eventually kill their host, unlike typical parasites which usually do not.
  • What is an example of a coevolutionary arms race in predation?
    The speed of cheetahs and springboks is an example of a coevolutionary arms race in predation.
  • What are the three main types of exploitation interactions in ecological communities, and how does each type benefit one organism at the expense of another?
    The three main types of exploitation are predation (predator kills and eats prey), herbivory (herbivore consumes plants, algae, or photosynthetic bacteria), and parasitism (parasite lives on or in a host, taking resources). In each case, one organism benefits while the other is harmed.
  • Describe two major types of mimicry used by prey as defense mechanisms and explain how each type benefits the organisms involved.
    Batesian mimicry is when a harmless species mimics a harmful one to deter predators, benefiting only the mimic. Mullerian mimicry is when two or more harmful species share similar warning coloration, mutually reinforcing their unpalatability and benefiting all involved.
  • Differentiate between ectoparasites, endoparasites, and parasitoids in terms of their relationship with the host and the typical outcome for the host.
    Ectoparasites live on the outside of the host (e.g., ticks), endoparasites live inside the host (e.g., roundworms), and both usually do not kill the host. Parasitoids, however, lay eggs in or on the host, and their larvae consume the host, typically resulting in the host's death.
