An adaptation is a trait that makes a living thing better able to survive in its surroundings.
Adaptations can be grouped into three types: structural, physiological, and behavioral.
Structural adaptations are traits that involve the physical structure or anatomy of an
organism. Physiological adaptations are traits that involve the internal functions or
chemistry of an organism, such as the presence of certain enzymes necessary to digest
food. Behavioral adaptations are inherited traits that help an organism survive and
reproduce in a given environment, or responses to the environment such as birds laying
eggs in nests or migrating to another geographical area with the change of seasons.
