Which is a result of a seasonal change (meaning a change that happens over and over at a certain time of a year)?
kodGreya [7K]

Answer: C. Birds moving south when the weather gets colder

Seasonal change is the change in season due to change in abiotic factors like weather conditions, sunlight availability, wind direction etc. Seasons change from summer to winter, winter to summer, summer to spring etc. These seasonal changes affect the life of biological communities including plants and animals.  Some organisms adapt to changing seasonal conditions but others completely avoid them by migrating to other places where weather conditions are suitable for their survival. Therefore, birds moving south when the weather gets colder is because of seasonal change as birds cannot tolerate cold weather conditions.
