What term describes organisms leaving a population?

Explanation:
When organisms leave a population, the term is emigration. It specifically describes departure from the group, which can reduce the source population and influence gene flow between populations. Immigration would be the opposite—entering a population. Migration is a broader term for the movement of individuals or groups from one area to another, often seasonally, and isn’t focused on leaving a particular population. Adaptation refers to inherited traits that improve fitness, not to movement between populations. So emigration is the precise term for leaving.
