Light has enough energy to influence the atoms and molecules of any organism.Also it has/produces heat which can be sensed by the sensory mechanisms of the organism.Some examples are photropism in plants, turning of sunflower towards sun,etc.
A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical
Stimulus?
The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
exagerrates the stimulus
The answer to this would mose probabaly be a stimulus. Because there are 2 types of stimuli Internal Stimulus and External Stimulus and so it has to be either one of these but the answer is stimulus.
It is a response called phototropism, where the plant grows towards light as a result of the stimulus of light perception.

The stimulus in the pupil reflex would be light

Tropism is the movement of a plant away from or toward a stimulus. The most easily found example of tropism is a plant's response to light. Plants tend to grow toward the light. This tendency is called 'phototropism'.

An organism responds to a stimulus.
A stimulus is any change in the environment that prompts a response from an organism. An example of an external stimulus in plants is light, which influences processes like phototropism, where plants grow towards a light source. An internal stimulus could be the concentration of water within the plant, which can trigger responses such as closing stomata to reduce water loss during drought conditions.
Complexity
)Movement or activity of an organism in response to a stimulus such as light.
Yes, that's correct. Tropism is the growth or turning movement of a plant in response to a stimulus such as light, gravity, or touch. Plants can exhibit positive tropism by growing towards a stimulus or negative tropism by growing away from a stimulus.
