Question

To. If each of the four processes controlling the growth rate of a particular population (births, deaths, immigration, and emigration) were dominated by positive feedbacks, we would expect the population in question a. to grow until the planet was covered with members of that population b. to rapidly decrease until it went extinct c. either a or b are possible d. to reach a stable equilibrium, to which it would tend to return following an perturbations e. to express approximately stable cycles, moving back and forth from relatively high densities to relatively low densities

Explanation / Answer

The answer is C because Positive Feedback is defined as a mechanism or a Circular chain of effects that increases change. Also, in an ecosystem if there is a factor contributing Positive Feedback, the other traits align themselves in such a way that the feedback is incresed.

In the given scenario where Births, Deaths, Immigration and Emmigration are dominated by Feedback meaning each factor is contributed to the maximum by the others. Considering Births and Immigration indicate, that the population of that species increases until the Earth is full with the organism.

On the other hand, positive feedback of Death and Emmigration indicate that this would continue until the species in Extint.
