Detailed explanation-1: -Therefore, sensitivity is the ability of an organism to respond to external stimulus.
Detailed explanation-2: -Internal stimuli are factors located inside the body that are detected and cause a response. Examples of internal stimuli are oxygen levels, blood sugar and pH levels, water levels, and internal temperature. If any of these conditions are too high or too low, the body will respond in a way to get back to homeostasis.
Detailed explanation-3: -The organisms can detect the changes using their sensory organs. The sensory organs can detect external changes (such as temperature, light, sound, etc.) or internal changes (loss of energy results in hunger). The sensory system signals the changes to the mind which elicit a response.
