Detailed explanation-1: -Anything that causes an organism to react or respond is called a stimulus (plural: stimuli). Stimuli can be external (outside the organism) or internal (inside the organism).
Detailed explanation-2: -Receptors. Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus.
Detailed explanation-3: -Responsiveness. All living things are able to respond to stimuli in the external environment. For example, living things respond to changes in light, heat, sound, and chemical and mechanical contact. To detect stimuli, organisms have means for receiving information, such as eyes, ears, and taste buds.
Detailed explanation-4: -What is a response? Response: how the organism reacts to a stimulus and results in a change in behavior. (It is a fancy way of saying “effect”.) Example: Getting a drink when you are thirsty.
