Final answer:
Migration enhances survival by allowing animals to find better resources in different areas.
Step-by-step explanation:
Migration is the long-range seasonal movement of animals. It is an evolved, adapted response to variation in resource availability, and it is a common phenomenon found in all major groups of animals. For example, birds fly south for the winter to get to warmer climates with sufficient food, and salmon migrate to their spawning grounds.
Migration enhances the survival of individuals because it allows them to find better resources, such as food and mates, in different areas. By moving to more favorable environments, animals can increase their chances of surviving and reproducing successfully.
Migratory animals, such as Canada geese, have evolved to undertake long and energetically demanding journeys. While migration does require a significant amount of energy expenditure, the benefits of accessing better resources can outweigh the costs.
