L. Investigate how organisms respond to external stimuli found in the environment (such as phototropism and fight or flight) In this educational video for kids, we explain stimuli and responses. Introduction to Sensation In more advanced animals, the senses are constantly at work, making the animal aware of stimuli, such as light or sound or the presence of a chemical substance in the external environment, while monitoring information about the organism’s internal environment. Animals normally only respond to stimuli which they select; they filter out certain stimuli that surround them, and react to others they choose to accept. The amount of sensitivity can range from Definition of Behavior Behavior is anything an animal does involving action and/or a response to a stimulus. Reflex, in biology, an action consisting of comparatively simple segments of behaviour that usually occur as direct and immediate responses to particular stimuli uniquely correlated with them. Response to stimuli examples reveal the fascinating ways in which creatures react to changes around them. This responsiveness is not a passive reaction but rather a complex, often highly orchestrated series of events involving signal […] Key Stimuli Certain innate behaviors can be produced in all individuals of the same species. It uses its keen sense of sight to search for fish in the lake 6. For example, plants respond to light stimuli by growing towards it, and animals respond to danger stimuli by fleeing or fighting.
