How does an organism respond to an external stimulus?

How does an organism respond to an external stimulus?

An organism will respond to a stimulus by modifying its behavior, or what it’s doing. Stimuli can be broken into either good or bad. If something is good, a living thing will behave in a way that increases the stimulus. If something is bad, a living thing will behave in a way that decreases the stimulus.

What are some examples of internal and external stimuli?

Stimuli can be external or internal. An example of external stimuli is your body responding to a medicine. An example of internal stimuli is your vital signs changing due to a change in the body.

What are internal and external responses?

A character’s internal responses refer to his or her feelings, desires, thoughts, and motivations. External responses — A character’s external responses refer to his or her actions and decisions.

How can an organism respond to an internal stimulus?

Animals receive stimuli through receptors. The stimuli travel along the sensory nerve to the brain, and then the processed information returns along the motor neuron. The reaction is a response to the stimulus in the form of muscle movements, a feeling of heat, cold, pain.

What is an example of a response to stimuli in a living organism?

A dog salivating at the smell of food, a flower opening in sunlight and a worm crawling towards moisture are examples of organisms responding to stimuli from their surroundings. All organisms respond to their surroundings in order to improve their chances of survival and reproduction.

What internal factors do organisms respond to?

what are two internal factors that organisms respond to? body temperature and hormone levels.

What is internal stimuli and external stimuli?

An external stimulus is the one which the organism receives from its external environment. An internal stimulus is the one which arises within the body. The external stimulus includes touch and pain, vision, smell, taste, sound, and balance. Examples of internal stimulus include hunger, thirst, and emotional states.

What are three examples of stimulus and response?

Examples of stimuli and their responses:

  • You are hungry so you eat some food.
  • A rabbit gets scared so it runs away.
  • You are cold so you put on a jacket.
  • A dog is hot so lies in the shade.
  • It starts raining so you take out an umbrella.

Do all organisms respond to stimuli?

Anything that causes a living organism to react is called a stimulus. All living organisms respond to their environment. Response to stimuli is an important characteristic of life.

What is an example of a response to stimuli in a living organism quizlet?

What are some examples of response in organisms?

What are the two types of stimuli?

There are two main types of stimulus –the external stimulus and the internal stimulus.

These sensory stimuli are activated by external changes.

  • Pain and touch: Pain is the stimulus that can cause a major response from the body.
  • Vision: Vision stimuli are sensed by a special type of neuron known as photoreceptor cells.

How do different organisms respond to stimuli explain with examples?

The plant responds to many types of external stimuli such as light, gravity, weather, and touch. The response of a plant is either positive (grow towards the stimulus) or negative (grow away from the stimulus). For example, phototropism is the plant’s response to stimulus, i.e. sunlight.
