Question

"Most populations demonstrate _____ growth, in which the population size increases exponentially until it levels off near the carrying capacity (K value) of the habitat for that species.
a) exponential
b) intrinsic
c) logistic
d) extrinsic
e) logarithmic"

Answer 1

Answer:

The correct answer is c) logistic

Explanation:

Logistic growth occurs during a population growth when the resources are limiting. During logistic growth sigmoid (S-shaped) growth curve is produced when population size is placed over time.  

In logistic growth first the population increases slowly then after some time it increase on the logarithmic phase until it levels off near the maximum carrying capacity due to environmental resistance. Beyond this maximum carrying capacity growth rate does not increase and becomes constant.

This generates an s-shaped curve called a sigmoid curve which shows the logistic growth. So the correct answer is c.
