Animals adapt to changes in their environment through various mechanisms such as changing their behaviors, physical characteristics, and habitats. They may develop new feeding habits, alter their migration patterns, adjust their reproductive strategies, or even evolve new physical traits to better survive in the changing conditions. Additionally, some animals may seek out new habitats that better suit their needs or form symbiotic relationships with other species to increase their chances of survival. Overall, adaptation is a key survival strategy for animals to thrive in ever-changing environments.
