What is a change in an organisms surroundings that provides a response?
A stimuli or stimulus is a change in an organisms surroundings that provokes a response from the organism.
How do organisms react to a stimulus?
Practically anything can be a stimulus, so organisms can respond to them in just about any way. The definition of 'stimulus' and 'response' are a little paradoxical in this context in that a stimulus is anything that provokes a response and a response is anything done to react to a stimulus. Perhaps some examples will make it clearer: if a predator grasps a lizard's tail (stimulus) it will detach the tail and escape (response). If the weather is excessively hot (stimulus), a plant will close the stomata in its leaves to conserve water (response). If a laboratory mouse notices a new object in its cage (stimulus), it will go investigate it (response).
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback
Cells that carry out a response to a stimulus are called?
effector
Anything that causes a response in an organism is called a?
Stimulus.

What is a plant response to a stimulus called?

A change in an organism's environment that causes the organism to react is called?
The change is actually a stimulus and when the organism reacts to the stimulus, it becomes a response. Overall, The answer is a stimulus.
A reaction to a stimulus is called a?
A stimulus evokes a response.
What is a naturally occurring reaction to a particular stimulus?
The reaction to a stimulus is called a response. An intensified stimulus usually evokes a more intense response. Of course the type of response to a stimulus depends on the nature of the stimulus. Scream at someone and they likely will feel verbally attacked. The screaming is the stimulus, feeling attacked is the response.
When salivation occurs in response to a previously neutral stimulus it is called a?
Conditioned Stimulus
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback
Cells that carry out a response to a stimulus are called?
effector
Random movement in response to a stimulus is called?
Kinesis
Anything that causes a response in an organism is called a?
Stimulus.
