Question

Asymptote is a logistic growth curve is obtained when-

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

Answer 1

The correct option is B

K = N

The correct option is B.

The explanation for the correct option:

1. A growth curve represents population growth over a period of time.
2. Asymptote in a logistic curve is obtained when carrying capacity(K) is equal to the number of individuals in the population(N).
3. The line of the graph will be constant up to a point when there is an increase in population or decrease in resources (due to various reasons).

The explanation for incorrect options:

Option A:

When r=o, the population is not increasing, it is stable.

Option C:

When K>N, the population grows and the curve is not asymptote.

Option D:

When N>K, the population growth becomes negative and it shrinks back to a population size at which the growth rate becomes zero.

The final answer: Asymptote in a logistic growth curve is obtained when K = N.
