The point on a logistic curve where a small change could cause population to either increase towards carrying capacity or decrease towards extinction is called ... a) a stable equilibrium. b) an unstable equilibrium. c) an inflection point. d) the maximum sustained yield. e) the open-access equilibrium.

b) an unstable equilibrium.

Explanation:

A logistic curve is a sigmoidal curve. it is popularly known as the S - curve and is used to model the functions which increases or rises gradually at first and then more rapidly in them middle portion and finally slows down at last.

It is mainly used for converting the logarithm of odds into the probability. The point on the logistic curve the population can either increase towards a carrying capacity or it can decrease towards the extinction by a small change is called as the unstable equilibrium.
