|
Answer» Solution :• 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 population density (N) in relation to TIME (t) results in a sigmoid curve. Here, r is intrinsic rate of NATURAL increase and K is carrying capacity of the environment. This type of population growth is called Verhulst-Pearl LOGISTIC Growth and is described by the • `(dN)/(dt) = rN ((K - N)/(K))(dN)/(dt) = rN (1 - N/K)` `(1 - N/K)` Environmental resistance. |
