              Response to Stimuli

                   Anything that triggers a reaction in an organism is called a stimulus.
                     (plural-stimuli)
                   The reaction of the organism to the stimulus is called a response.
                   All living things respond to stimuli.
                   Non-living things do not show any response to stimuli.
                   We can perceive the changes in the environment or stimuli with the help of
                     our sense organs like -
                        Eyes
                        Nose
                        Tongue
