Question

The given figure represents different factors affecting population density (N). If B = natality, D = mortality, E = emigration and I = immigration; then select the incorrect option regarding these. (A) B and D are most influential factors under normal conditions while I and E become important in special conditions (B) In a new habitat just being colonised, I becomes more important than B (C) B and I cause positive changes in N (D) I is generally equal to E

Immigration is not necessarily equal to emigration in a population.

Q. The given figure represents different factors affecting population density $(N)$ . If $B =$ natality, $D =$ mortality, $E =$ emigration and $I =$ immigration; then select the incorrect option regarding these.

$B$ and $D$ are most influential factors under normal conditions while $I$ and $E$ become important in special conditions

In a new habitat just being colonised, $I$ becomes more important than $B$

$B$ and $I$ cause positive changes in $N$

$I$ is generally equal to $E$
