The initial verbal equation for population change includes 'Immigrants entering population' and 'Emigrants leaving population.' What simplification is made when the text proceeds to develop mathematical models for population growth?

  • A: The models assume zero births.
  • B: The models assume zero deaths.
  • C: The models initially ignore the effects of immigration and emigration.
  • D: The models consider only very large populations.

Explanation

The text explicitly states: 'For now, we will simplify our discussion by ignoring the effects of immigration and emigration.' This simplification allows the focus to be solely on births and deaths for developing the initial mathematical models.
