What are the 3 different forms of adaptation?

The three different forms of adaptation are structural, behavioral, and physiological adaptations. Structural adaptations involve physical features of an organism, such as the shape of a beak or camouflage. Behavioral adaptations are the actions or behaviors that organisms exhibit to survive, like migration or foraging strategies. Physiological adaptations refer to internal processes or functions, such as temperature regulation or metabolic changes, that help organisms thrive in their environments.
