What is the main difference between logistic and exponential growth curves? a. logistic growth curves never increase exponentially. b. logistic growth curves stabilize when carrying capacity is reached. c. logistic growth curves decrease before they increase. d. logistic growth curves are identical to exponential growth curves.

b.  Logistic growth curves stabilize when carrying capacity is reached.

Explanation:

A logistic growth curve is the S shaped curved it depicts the logistic growth in the population of a species. The logistic growth refers to the per capita growth of the population of the species when the population size approaches towards the maximum the carrying capacity of the resources of the environment get limited. This can be represented by the S shaped curve in which the population increases gradually at first, more rapidly in the middle and then population growth at the end is limited this is shown in the leveling off curve.

In the exponential growth the population of a species increases rapidly due to abundance of resources. It is not limited by the carrying capacity of the ecosystem. It can be represented by a J shaped curve.

On the basis of the above description, b.  Logistic growth curves stabilize when carrying capacity is reached. is the correct option.

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.
