Q. The logistic population growth is expressed by the equation
A) dN/dt = rN
B) dN/dt = rN[(N − K)/N]
C) dt/dN = Nr[(K − N)/K]
D) dN/dt = rN[(K − N)/K]
Explanation
[Solution from source] Logistic (Verhulst-Pearl) growth is dN/dt = rN[(K − N)/K]: growth slows as N approaches the carrying capacity K. dN/dt = rN is exponential growth, and the other forms invert either the derivative or the term (N − K). Answer (4).
