Question

select the correct answer.
in a certain ecosystem, the number of cheetahs is lower than their prey, gazelles. this causes the number of prey to increase since they didnt have as many predators. this increase creates an increase in cheetahs. what is this an example of?
a. positive feedback
b. allogenic succession
c. autogenic succession
d. negative feedback

Explanation:

Positive feedback describes a cycle where a change in a system leads to further amplification of that change. Here, fewer cheetahs let gazelle numbers rise, which then causes cheetah numbers to increase—each change reinforces the other, fitting positive feedback. Allogenic and autogenic succession refer to ecosystem development driven by external or internal factors respectively, which is not the case here. Negative feedback would involve a change that reverses the initial shift, which does not occur in this scenario.

Answer:

A. positive feedback
