Reflex Action is the term that describes the way an organism responds to stimuli. It receives stimuli through its senses and reacts with movement, or for a plant growing towards or away.
A physical or chemical change in an organism's environment that triggers a response is referred to as a stimulus. This stimulus can cause the organism to react in a way that helps it adapt to the changed conditions, such as by moving to a different location, changing its behavior, or adjusting its metabolic processes. For example, plants may respond to changes in light levels by altering their growth patterns.
A signal to which an organism responds is called a stimulus. It can be any environmental change or cue that triggers a response or behavior in an organism. This response can range from simple reactions like moving away from a harmful substance to complex behaviors like mating rituals in animals.
