    A. a and b only
    B. the fig wasp can be thought of as a "service mutualist" since it pollinates the plant
    C. both species gain an advantage (in terms of survival and reproduction) from other species
    D. the fig wasp is a commensalist, since it pollinates the plant, but gains nothing in return

    one species in a mutualism penalizing the other for "cheating"
  10. In models of disease, the threshold density of susceptible individuals (ST) is:
    can be reduced by adding susceptible (healthy) individuals to the population
  11. In disease ecology "SIR" models indicate that:
    host population size, as well as reproductive, death, and disease-recovery rates, are all important in predicting the negative consequences of different diseases in that population
