d. None of the choices is correct.
What are some conditions that might lead to a mutualistic organism becoming a predator/parasite. Select all that apply.
A. Mutualistic nitrogen fixation bacteria might reduce the competitive ability of their host plants in environments with high N availability, because of the energetic costs to the plants of supporting the bacteria
B. none of the above
C. Mutualistic nitrogen fixing bacteria can become parasites in soil with low nitrogen availability because of the energy costs to the plant of supporting the bacteria
D. A mutualist fish species that feeds on ectoparasites of another fish species, might switch to feeding/removing important host tissue or secretions when ectoparasite abundance is too low.
