Asymptote in a logistic growth curve is obtained when

Options

A. he value of 'r' approaches zero
B. K = N
C. `K gt N`
D. `K lt N`

Answer

B

Explanation

A population growing in a habitat with limited resources shows logistic growth curve.
For logistic growth
`(dN)/(dt)=rN((K-N)/(K))`
If `K=N` then `(K-N)/(K)=0`
`:.` the `(dN)/(dt)=0` ,
the population reaches asymptote .
