*Natality- The ratio of the number of births to the size of the population; birth rate*Immigration- the act of entering another place *Mortality- death rate *Emigration- the act of leaving one place
Reasons for the Exponential Growth, Plateau, and Transitional Phase: • Addition and Removal of Coyotes
