In change in population size Nt=N0+B+I−D−E. I, B, D stands for rates of
The correct option is B Immigration, natality, mortality
Population growth is defined as
the increase in the number of individuals in a population. The rate of
population growth is expressed by the number of individuals added per unit
population in a specified time. Population growth rate actually measures how
fast a population is changing. In general, there are some factors that
contribute to the change in the size of a population, from a one-time step to
the next. Some of these factors determine the increase in population size,
which are births and immigration. Whereas, the other factors lead to a decrease
in population size, which are deaths and emigration. If N0 is the
initial size of a population and Nt is its size after a specified
time interval, then the following general equation helps to predict the
population size at a future time.
Nt = N0 + B
+ I - D − E
Here, within a specified time interval, B stands
for natality rate, D is the mortality rate, I stands for immigration rate, and E
equals the emigration rate.
