Sagot :

Exponential population growth is an example of a positive feedback loop. So option b. is correct.

Exponential population growth occurs when each set of parents has more children than there are parents, and then these children grow up to become parents themselves. The phenomenon of system components both impacting each other creates a feedback loop. A positive feedback loop is a circumstance in which performing an action causes more performances of the action. A population can temporarily exceed the carrying capacity.
