The movement of individuals to and from a population is defined as "migration." Therefore, the correct answer is:
O Migration
Migration can involve animals, birds, fish, insects, or humans moving from one habitat to another, either seasonally or permanently, for a variety of reasons like climate, food availability, mating, or other ecological factors.
For each of the incorrect options:
- "Composition" refers to the make-up of a population, including factors such as age, sex, genetic composition, etc.
- "Distribution" refers to how individuals within a population are spread out across a given area or space.
- "Dynamics" refer to the changes in population size and structure over time, including birth rates, death rates, immigration, and emigration.
Again, of these choices, "Migration" is specifically the term used for the movement of individuals to and from a population.
