Detailed explanation-1: -Stimulus like food. Prey will cause a reaction from a hungry animal.
Detailed explanation-2: -A stimulus is a signal from the animal’s body or its environment. It is a form of energy-light waves or sound vibrations, for example. All but the simplest animals receive a stimulus-light, sound, taste, touch, or smell-through special cells called receptors, located in many places on or in the body.
Detailed explanation-3: -An example of stimulus in animals is the sight of another animal (especially predators) where they respond by fleeing away or fighting. In animals, most of the responses as a result of stimulus are of instinctual nature.
Detailed explanation-4: -There are different types of stress responses in an animal in response to stressors: Physiological responses, Behavioural responses, Psychological responses, and/or Physical responses (fight or flight).
