NEET Solved Paper 2017 Question 29

Question: Asymptote in a logistic growth curve is obtained when

Options:

A) K < N

B) The value of ‘r’ approaches zero

C) K = N

D) K > N

Show Answer

Answer:

Correct Answer: C

Solution:

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