Answer Details
A change in the environment of an organism is termed a stimulus. A stimulus is any change or signal in the environment that can be detected by an organism and can lead to a response or reaction. Stimuli can come in many forms, such as light, sound, touch, temperature, and chemicals. When a stimulus is detected, it triggers a response in the organism, which is a specific reaction or behavior to the stimulus. For example, a plant may respond to a stimulus of light by bending towards the light source, or an animal may respond to a stimulus of food by moving towards it.
