Behavior refers to the actions or reactions of an individual, often in response to external or internal stimuli. It encompasses a wide range of activities, including how people interact with each other, how animals respond to their environment, and even how plants react to light. Understanding behavior is essential in fields like psychology, biology, and sociology, as it helps explain why individuals or groups act in certain ways. Factors influencing behavior can include genetics, environment, culture, and personal experiences. For example, children may behave differently based on their upbringing, while animals might exhibit specific behaviors to adapt to their habitats. Studying behavior allows researchers to identify patterns and make predictions about future actions.
