Read the following text and answer the following question on the basis of the same : Growth of population with time shows specific and predictable patters. Two types of growth patter of populaiton are exponetial and logistic growth . When resource in the habitat are unlimited each species has the ability to relize fully its innate potential to grow in number . Then the population gorws in exponential fashion . When the resource are limited growth curve shows an inital slow rate and then it accelerates and finally slows giving the gorwth curve which is sigmoid . The population growth is generally descibed by the following equations : dN//dt = rN(K-N)//K What does 'r' represent in the given equation ?

Study the population growth curves in the graph given below and answer the questions which follow : (i) Identify the growth curves ‘a’ and ‘b’. (ii) Which one. of them is considered a more realistic one and why ? If (dN)/9dt)=rN((K-N)/K) is the equation of the logistic growth curve, what does K stand for ? (iv) What is symbolised by N ?

According to the logistic population growth model, the growth rate is independent of
