Living vs Non-living Things
What Are Living Things?
Living things are organisms that exhibit the characteristics of life. They can grow, reproduce, respond to stimuli, and adapt to their environment. Examples include:
- Humans
 - Animals (e.g., dogs, cats)
 - Plants (e.g., trees, flowers)
 - Microorganisms (e.g., bacteria, fungi)
 
Characteristics of Living Things
- Growth: Increase in size and number of cells.
 - Reproduction: Ability to produce offspring.
 - Response to Stimuli: Reacting to changes in the environment.
 - Metabolism: Chemical processes that occur within a living organism.
 - Adaptation: Ability to adjust to environmental changes.
 - Homeostasis: Maintaining a stable internal environment.
 
What Are Non-living Things?
Non-living things do not exhibit the characteristics of life. They do not grow, reproduce, or respond to stimuli. Examples include:
- Rocks
 - Water
 - Air
 - Furniture
 
Differences Between Living and Non-living Things
| Characteristic | Living Things | Non-living Things | 
|---|---|---|
| Growth | Grow and develop | Do not grow | 
| Reproduction | Can reproduce | Cannot reproduce | 
| Response to Stimuli | Respond to stimuli | Do not respond | 
| Metabolism | Have metabolic processes | No metabolism | 
| Adaptation | Adapt to environment | Do not adapt | 
| Homeostasis | Maintain homeostasis | No homeostasis |

Tuity Tip: To easily remember the characteristics of living things, think of the acronym "MRS GREN": Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, and Nutrition.
