This occurs during unfavourable conditions and is most commonly observed in insects, especially in arthropods. In biology, a stimulus is defined as a "detectable change (physical or chemical) in an organism's environment that results in some functional activity.". Stimulus: A stimulus in the literal word means, a change in an environment. The sense organs, including the eye, contain receptors that are sensitive to stimuli and respond with reflex actions. Unlike animals, plants can't run, fly, or swim toward food or away from danger. The combination of biology and society is what makes us what we are and do what we do. The temperature is the stimulus, and the individual then protects themselves by pulling their hand away. We classify all stimuli the same, that is, a stimuli is a thing that provokes a response in a biological system. This includes such subjects as the cell, genes, inheritance, microorganisms, plants, animals, and the human body.
