Question

The equation of Verhulst-Pearl logistic growth is
\(\frac {dN}{dt}=rN[\frac {K-N}{K}]\)
from this equati on, K indicates:

• A. intrinsic rate of natural increase
• B. Biotic potential
• C. Carrying capacity
• D. Population density

Answer 1

The Correct Option is C

The Verhulst-Pearl logistic growth model represents population growth with a limiting factor, \( K \), which is the carrying capacity of the environment.

- \( r \) represents the intrinsic rate of natural increase.

\[ \begin{array}{|c|c|} \hline \textbf{Symbol} & \textbf{Meaning} \\ \hline K & \text{Carrying Capacity (Maximum population size)} \\ r & \text{Intrinsic Rate of Natural Increase} \\ \hline \end{array} \]

- \( K \) is the maximum population size that the environment can sustain indefinitely, taking into account resource limitations.

Thus, the correct answer is (3) Carrying capacity.
