of Eastern Cottontail Rabbits in Red Forest increased, food resources became scarce. The number of predators of Eastern Cottontail Rabbits C. decreased. Eastern Cottontail Rabbits in a distant forest ecosystem experienced severe D. disease. Organism Interactions & Population Dynamics 63. The organisms within an established ecosystem interact and form relationships with each other. This interdependence causes ecosystems to remain relatively stable for hundreds and thousands of years. For example, a population's size is often held in check by one or more environmental factors or another species. Which of the following would most likely negatively affect a population's size? I. a drought II. a sudden change in climate III. an increase in food supply immigration of a non-native IV. species A. III only III and IV B. only I, II, and IV C. only D. I and II only
