For example, if a loud bang wakes you up in the night, the fright makes your heart beat faster, you breathe faster, and your heart pumps more blood to the brain. The result is that you suddenly become fully awake and attentive. This natural response helps you to stay safer. Adaptation is the process that helps an organism survive in its environment. A polar bear, for example, will struggle to survive in a hot climate because the temperature will be too much for it.
In summary, for any organism to be considered alive, it must have all these characteristics. Skip to content Characteristics of living things. Characteristics of living things. Made up of cells. Obtain and use energy. Growth and development. For humans it's sight, smell, taste, touch, and hearing.
Not all organisms have all of these, and some have completely different senses. For example, sharks can sense electrical differences between water and other fish, which helps them find their food. Additionally, elephants can sense vibrations created by other elephants even ten miles away.
This helps them communicate over long distances. The delicious smell given off by pizza is a stimulus. The receptors in the nose of a lurking pug sense the stimulus and send information about it to the brain, or control center.
Then, the brain decides how the pug should respond to the stimulus. The pug starts drooling as he prepares to devour the pizza.

An example would be the receptors on our skin which sense a stimulus like temperature or pain. Then, information is sent to the nervous system, our control center , which decides how the body should respond. The response is called the effector.
This could be shivering when you're cold in order to warm up or even just putting on a coat. A stimulus can be external , like seeing something happening around you, but it can also be internal. For example, if you haven't eaten in a while, you start to feel hungry.
Hunger is the internal stimulus which makes you eat. So why is this interaction so important? It helps us avoid danger, find food, and communicate with people we know. It also helps us maintain homeostasis , a stable environment within the body. You would not be able to survive without the ability to respond to the environment. Response to stimuli is an important characteristic of life. Anything that causes a living organism to react is called a stimulus plural is stimuli Stimuli can be external or internal.
The term used to describe the ability of an organism to maintain balance in its internal environment is called 'homeostasis'. What are examples of the 7 characteristics of life?
The seven characteristics of life include: responsiveness to the environment; growth and change; ability to reproduce; have a metabolism and breathe; maintain homeostasis; being made of cells; and. What is the 7 characteristics of life? Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution.
Some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive. Why do we need to respond to stimuli? Living things respond to their environment Response to stimuli is an important characteristic of life. It helps the organism to stay in balance. What are 2 main reasons that organisms respond to stimuli?
All living things are able to respond to stimuli in the external environment. For example, living things respond to changes in light, heat, sound, and chemical and mechanical contact. To detect stimuli, organisms have means for receiving information, such as eyes, ears, and taste buds. How do you respond to stimuli in your environment? An example would be the receptors on our skin which sense a stimulus like temperature or pain. Then, information is sent to the nervous system, our control center, which decides how the body should respond.
The response is called the effector. What is an example of responsiveness? Responsiveness is nothing but to respond as quickly as possible to a situation. Example: a customer drops a mail regarding some specific information about a product. Now responsiveness can be traced out from how fast you reply to this mail with the desired information.
