Here's why:

* Traits are indeed characteristics of living things. They describe the physical and behavioral features of an organism. Examples include things like eye color, height, how an animal hunts, or how a plant responds to sunlight.

* However, not all traits are unique to living things. For example, a rock can have traits like color, shape, and size.

To be more precise, we could say:

* Living things possess a unique set of traits that distinguish them from non-living things. These include:

* Organization: Living things are made up of cells and have a complex internal structure.

* Metabolism: They carry out chemical reactions to obtain and use energy.

* Growth: They increase in size and complexity over time.

* Reproduction: They create new individuals of the same kind.

* Response to stimuli: They react to changes in their environment.

* Adaptation: They can change over generations to better survive in their environment.
