Question

Q4.14. To the right are two graphs showing zero growth isoclines in phase space for plant species A and B, with insect herbivores absent (top) and present (bottom). Based on your interpretation of these graphs, which of the following is the most likely impact of insect herbivory on the competitive relationship between Species A and B? Herbivory promotes coexistence of Species A and B. Herbivory results in competitive exclusion of Species A by Species B. o Herbivory results in competitive exclusion of Species B by Species A. Herbivory has no effect on competition between Species A and B.
