Detailed explanation-1: -Behavior can also be defined more narrowly as a change in the activity of an organism in response to a stimulus, an external or internal cue or combination of cues. For example, your dog might start drooling-a change in activity-in response to the sight of food-a stimulus.

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: -You are hungry so you eat some food. A rabbit gets scared so it runs away. You are cold so you put on a jacket. A dog is hot so lies in the shade.

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). The response depends on the choice the animal partakes in, when it is faced with danger that causes distress.

Detailed explanation-5: -Instinct, imprinting, conditioning, and imitation are the four types of animal behavior.
