Question

$N^{\prime}$ is the population density of time $t$ then its density at time $t+1$ is

$\left.\left.N_{t+1}=N_{t}+ [\mid B+I\right]\right]-[|D+E|]$

Vedclass · Accepted Answer

$\left.\left.N_{t+1}=N_{t}+[ \mid B+I\right]\right]-[|D+E|]$

Vedclass · Answer

$N^{\prime}$ is the population density of time $t$ then its density at time $t+1$ is

$\left.\left.N_{t+1}=N_{t}+ [\mid B+I\right]\right]-[|D+E|]$

We can see from the above equation that population density increases if the number of birth plus number of immigrants ( $B+I$ b is more than the number of death plus the number of emigrants $(D+E)$

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
