Asymptote in a logistic growth curve is obtained when:
-
- K = N
- K > N
- K < N
- The value of 'r' approaches zero
Correct Option: A
In logistic growth curve, the curve has an upper a symptote known as carrying capacity (K) is obtained when the maximum population size is at dN/dt = 0. A population growing in a habitat with limited resources shows logistic growth curve.
For logistic growth
| = rN |  |  | ||||
| dt | K |
| If K = N then | = 0 | K |
| ∴ The | = 0 | dt |
the population reaches asymptote.
