Asymptote in a logistic growth curve is obtained when
1. The value of 'r' approaches zero
2. K = N
3. K > N
4. K < N
Answer:(2)
👉Logistic growth: No population of any species in nature has at its
disposal unlimited resources to permit exponential growth. This
leads to competition between individuals for limited resources.
Eventually, the ‘fittest’ individual will survive and reproduce.
👉In nature, a given habitat has enough resources to support
a maximum possible number, beyond which no further growth is
possible. Let us call this limit as nature’s carrying capacity (K) for
that species in that habitat.
👉A population growing in a habitat with limited resources show
initially a lag phase, followed by phases of acceleration and
deceleration and finally an asymptote, when the population density
reaches the carrying capacity. A plot of N in relation to time (t)
results in a sigmoid curve. This type of population growth is called
