Population Growth Rate

Which one is right for logistic model for population growth I. population growth rate increases as the size of population approaches the carrying capacity II. All individual have same effect on population growth III. There are unlimited natural resources IV. As population increases the competition goes on increasing select the correct combination.

The graph below shows the relationships of per capita population growth rate (r), fecundity (b) and age at first reproduction (alpha) in an animal speies What is the most important conclusion to be drawn from the graph ?

The relationship between population density (N_(t)) and population growth rate (R = N_(t+1) l N_(t)) in a certain animal species is shown below. Choose from the following graphs the appropriate populations growth patterns that would be obtained if the population is at the densities (I, II, III) shown in the graph above. [Note : THe y-axis in A to D is relative density that cannot be compared to the absolute density in the figure]

According to the 2001 census, the population growth rate of Lucknow is going to be an increasing. AP with first year’s rate as 5% and common difference as 5%, but simultaneously the migration, rate is an increasing GP with first term as 1% and common ratio as 2. If population on 31 December 2000 is 1 million, then find in which year will Lucknow witness its first fall in population?

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