Question

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.

please select the best answer from the choices provided

○ a
○ b
○ c
○ d

Explanation:

Exponential growth curves show unlimited, continuous increase with no upper bound. Logistic growth curves start with exponential-like growth but slow down and stabilize when the population reaches the environment's carrying capacity (the maximum number of individuals the environment can support). Option a is wrong because logistic growth has an initial exponential phase; option c is incorrect as logistic growth does not decrease before increasing; option d is false because the two curves are distinct.

Answer:

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