How do animals adapt to their environment, like the examples of camouflage in chameleons and migration in birds?

Animals adapt to their environment through various mechanisms, such as camouflage and migration. Camouflage, like in chameleons, helps animals blend in with their surroundings to avoid predators or sneak up on prey. Migration, as seen in birds, allows animals to move to different locations to find food, escape harsh weather, or reproduce. These adaptations help animals survive and thrive in their environments.
