Vedclass · Answer

(C) The figure illustrates the factors affecting population density $(N)$:$1.$ Natality $(A)$ refers to the number of births during a given period,which adds to the population density. Thus,$A$ represents an increase.$2.$ Immigration $(B)$ refers to the number of individuals of the same species that have come into the habitat from elsewhere during the time period under consideration,which adds to the population density. Thus,$B$ represents an increase.$3.$ Mortality $(C)$ refers to the number of deaths in the population during a given period,which reduces the population density. Thus,$C$ represents a decrease.$4.$ Emigration $(D)$ refers to the number of individuals of the population who left the habitat and gone elsewhere during the time period under consideration,which reduces the population density. Thus,$D$ represents a decrease.Therefore,the correct sequence is $A-$Increase,$B-$Increase,$C-$Decrease,$D-$Decrease. The correct option is $(c)$.

Study the figure and identify $A, B, C,$ and $D$ in relation to their effect on population density.
