What is a Living Thing?
A living thing is any organism that exhibits the characteristics of life, such as growth, reproduction, metabolism, response to stimuli, and adaptation.
Definition of Living Thing
Scientific Definition:
“A living thing is an organism that maintains homeostasis, undergoes metabolism, grows, adapts to its environment, reproduces, and responds to stimuli.”
Simple Definition:
“Anything that is alive, such as humans, animals, plants, and microorganisms, is called a living thing.”
Characteristics of Living Things
Growth & Development – Increase in size and changes in structure.
Reproduction – Ability to produce offspring.
Metabolism – Chemical processes that sustain life.
Response to Stimuli – Reacts to the environment (e.g., plants bending toward sunlight).
Adaptation & Evolution – Changes over generations to survive.
Homeostasis – Maintains internal balance (e.g., body temperature).
Cellular Organization – Made up of one or more cells.
Examples of Living Things
Humans
Animals (dogs, birds, fish)
Plants (trees, flowers, grass)
Microorganisms (bacteria, fungi, viruses*)
(*Viruses are debated because they need a host to reproduce.)
Conclusion
Living things are organisms that grow, reproduce, and respond to their environment. They are different from non-living things, which do not show these characteristics.

Here’s a clear and simple explanation for:
What is a Living Thing?
Meaning and Definition
Definition:
A living thing is any organism that shows the basic characteristics of life, such as growth, movement, reproduction, response to stimuli, and metabolism.
Meaning:
Living things are beings that are alive. They carry out essential life processes that non-living things do not.
Scientific Definition:
“Living things are organisms that have the ability to grow, reproduce, maintain homeostasis, carry out metabolism, and respond to their environment.”
Examples of Living Things:
- Humans
- Animals (dogs, birds, fish)
- Plants (trees, flowers, grass)
- Microorganisms (bacteria, fungi, protozoa)
Characteristics of Living Things:
| No. | Characteristic | Description |
|---|---|---|
| 1 | Growth | Increase in size or cell number |
| 2 | Reproduction | Ability to produce offspring |
| 3 | Metabolism | Chemical reactions in the body (e.g., digestion) |
| 4 | Response to Stimuli | Reacts to environment (e.g., light, touch) |
| 5 | Movement | Internal or external motion |
| 6 | Excretion | Removal of waste |
| 7 | Respiration | Energy production from food |
| 8 | Adaptation & Evolution | Changes over generations |
Non-Living Things (for contrast):
- Rocks
- Water
- Air
- Chairs
- Machines (even if they move or make sound)
Simple Trick to Remember:
“MRS GREN” – Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition
