If natality is represented by $-B$
If mortality is represented by $-D$
If immigration is represented by $-I$
If emigration is represented by $-E$
If population density is represented by $-N$
Then population density at time $t+1$ is represented by
$N_{t+1}=N_{t}-[(B+I)]-i$
$\left.\left.N_{t+1}=N_{t}+[ \mid B+I\right]\right]-[|D+E|]$
$N_{t+1}=N_{t}+[(B+I)]+[|D+E|]$
$\left.N_{t+1}=N_{t}-[\mid B+I)\right]+[|D+E|]$
The declining phase of a population occurs when
The standard of living is very badly affected by
With the help of suitable diagram describe the logistic population growth curve.
