Vedclass · Answer

(A) Population density changes due to four basic processes: $1$. Natality $(B)$: The number of births during a given period in the population that are added to the initial density. $2$. Mortality $(D)$: The number of deaths in the population during a given period. $3$. Immigration $(I)$: The number of individuals of the same species that have come into the habitat from elsewhere during the time period under consideration. $4$. Emigration $(E)$: The number of individuals of the population who left the habitat and went elsewhere during the time period under consideration. Natality and Immigration contribute to an increase in population density,while Mortality and Emigration contribute to a decrease. Therefore,Natality is the primary characteristic responsible for the increase in population.
