Detailed explanation-1: -The ability of an organism to respond to external stimuli is called sensitivity. For example, Plants grow towards light(external stimuli) sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survival.

Detailed explanation-2: -Animals receive stimuli through receptors. The stimuli travel along the sensory nerve to the brain, and then the processed information returns along the motor neuron. The reaction is a response to the stimulus in the form of muscle movements, a feeling of heat, cold, pain.

Detailed explanation-3: -Sensory Processing in Animals. The sensory system detects signals from the outside environment and communicates it to the body via the nervous system. The sensory system relies on specialized sensory receptor cells that transduce external stimuli into changes in membrane potentials.
