The Verhulst - Pearl Logistic Growth of population is characterised by:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Sigmoid curve
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 Verhulst-Pearl Logistic Growth.
= \(\frac{dN}{dt}\) = rN(\(\frac{K-N}{K}\))
Population growth curve a when responses are not limiting the growth, plot is exponential, b when responses are limiting
the growth, plot is logistic, K is carrying capacity
