If natality rate is parallel to mortality rate then population
A biologist studied the population of rats in a barn. He found that the average natality was $250$, average mortality $240$, immigration $20$ and emigration $30$. The net increase in population is
Which of the following is correct
$I.$ In a population, birth rate and death rate refer to per capita births and death respectively
$II.$ In nature, we rarely find isolated single individuals of any species
$III.$ The size of population for any species is stable phenomena
$IV.$ Ecological effects of any factors on a population growth are generally reflected in its size/population density
