Only external stimulus consciousness is the definition feature of living organisms as others can be done in labs also

Introduction
Living organisms are a diverse group of entities that include everything from simple single-celled bacteria to complex multicellular animals and plants. However, all living organisms share a common set of characteristics that define them as living.

The Defining Property of Living Organisms
The defining property of living organisms is that they are capable of carrying out the processes of life. These processes include:

1. Metabolism: Living organisms are capable of carrying out chemical reactions that allow them to break down food and convert it into energy, as well as build and repair their own tissues.

2. Growth and development: Living organisms are capable of growing and developing over time, changing in size, shape, and function.

3. Reproduction: Living organisms are capable of producing offspring that are similar to themselves, passing on their genetic information from one generation to the next.

4. Response to stimuli: Living organisms are capable of responding to changes in their environment, such as changes in temperature, light, or the presence of predators.

5. Homeostasis: Living organisms are capable of maintaining a stable internal environment, despite changes in their external environment.

Conclusion
In summary, the defining property of living organisms is their ability to carry out the processes of life, including metabolism, growth and development, reproduction, response to stimuli, and homeostasis. These characteristics are what distinguish living organisms from non-living entities and are what make them so fascinating and diverse.
