Question 7 • Biology A (The Living Earth A)

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

Answer
A
resources become scarce
B
birth rate increases
C
emigration decreases
D
carrying capacity is increased

Explanation

Exponential growth can continue while resources are plentiful, but as the population grows, food, space, or other resources may become scarce. This limits population growth and causes it to level off near the environment’s carrying capacity, producing logistic growth. Increasing the birth rate or reducing emigration would tend to increase population growth rather than limit it.
