For an instant, unlearned response, it does it with its reflex arc, which is made of 5 elements- (i)a receptor- a sensory organ, like an eye, ear, tongue or touch corpuscle (ii)sensory neuron, (iii)a coordinator neuron, (iv) a motor neuron and (v)an effector which normally is a muscle-either involuntary smooth or voluntary striped muscle.
A receptor receives the stimulus, a sensory neuron carries the impulse in the form of an electric impulse, a coordinator neuron takes the necessary suitable action, a motor neuron carries the decision to the effector and finally the effector brings out suitable response.
Lower animals lack an organized nervous system, but still the mechanism is more or less similar.
If you mean "What is an organism's reaction to physical stimuli? it is usually withdrawal or avoidance. It depends on what type of stimuli and what type of organism. Is the organism used to this type of stimuli? Is it a new strange stimuli? The question is not specific enough to answer thoroughly nor is it grammatically correct.
Stimuli are things in the environment that cause change. A reaction to a change in the environment is a reaction to a stimulus.
Change in activity due to stimuli from the environment refers to how an organism's behavior or physiological responses are altered in response to external factors such as light, temperature, or sound. This can involve an increase or decrease in activity levels depending on the specific stimulus present.

Stimuli is the plural form of "stimulus," which means something that is intended to enact a reaction in an organism.
stimuli
A stimulus is a detectable change in an organism's internal or external environment that leads to a response. It can be anything that triggers a reaction or behavior in an organism, such as a sound, light, smell, or touch.
it is a stimuli that an organism reacts to called.It is the characteristic feature of every living organism to respond to stimuli.

response?
Stimuli
Response to stimuli refers to a response to outside stimuli such as a noise or a smell. It is a term that refers to an organisms ability to respond to the outside environment.
Anything in the environment that affects the behavior of an organism is called a stimulus.
plant and animals
Phototactic stimuli are related to an organism's response to light, where they move towards or away from light sources. Chemotactic stimuli involve an organism's response to chemical signals in their environment, leading to movement towards or away from the source of the chemical. Both types of stimuli play important roles in an organism's survival and behavior.
