Movement of individuals into a population is called:

Explanation:
Immigration is the movement of individuals into a population. It increases population size by adding outsiders that arrive from elsewhere. Emigration is the opposite—individuals leaving the population. Migration is a broader term for movement between habitats or regions and isn’t specific to entering a population. Influx is a general term for arrival but isn’t the standard ecological term that specifically denotes individuals entering a population. So the correct term for entering a population is immigration.
