What does an s–shaped curve for population growth suggest
a) a delayed growth pattern
b) a logistic growth pattern
c) an exponential growth pattern

The correct answer is option B

The S-shaped graph (sigmoid) graph shows logistic growth. This is a pattern of growth in which the density of organisms increases slowly at first and then it increases fastly approaching an exponential  growth.

Then it declines in a negative direction which shows the resistance of environment.

All these make a combinely make a graph called S-shaped graph. Mathematically all these ups and down makes it a logistic growth pattern graph.
