Question

Asymptote in a logistic growth curve is obtained when :

• A. K = N
• B. K > N
• C. K < N
• D. The value of 'r' approaches zero

Answer 1

The Correct Option is A

A population growing in a habitat with limited resources shows logistic growth curve.
For logistic growth
$\frac{d N}{d t}=r N\left(\frac{K-N}{K}\right)$
If $K = N$ then $\frac{ K - N }{ K }=0$
$\therefore$ the $\frac{ d N }{ dt }=0$,
the population reaches asymptote.
