D. aestivation

Answer

Explanation

The seasonal movement of complete populations of animals to a more favourable environment is called migration. It is usually in response to uneven precipitation and lower temperatures resulting in a reduced food supply and is often triggered by a change in day length. Migration is common in mammals (e.g porpoises), fish (e.g., eels and salmon) and some insects but is most marked in birds.
