Topic Test

A muskrat population is growing exponentially. What might cause this population to enter logistic growth?

A. Resources become scarce.
B. Birth rate increases.
C. Emigration decreases.
D. Carrying capacity is increased.



Answer :

Final answer:

When resources become scarce, a population transitions from exponential to logistic growth. Increasing the carrying capacity can also trigger logistic growth.


Explanation:

Resources become scarce: When resources become limited, a population shifts from exponential growth to logistic growth as it reaches its carrying capacity, leading to a more stable growth rate.

Carrying capacity is increased: If the environment's carrying capacity is increased, it can support a larger population, causing the population to enter into logistic growth.

Birth rate increases and emigration decreases would not cause a population to enter logistic growth, as they do not directly impact the resources available or the carrying capacity of the environment.
