Which of these objects is NOT an organism?
Which of these objects is NOT an organism?
The answer is "a rock"
Organisms are living things. Living things have the ability to reproduce, grow, and breathe. They are made of cells. Unicellular organisms like paramecium are made of one single cell while multicellular organisms like trees are made of many. Nonliving things are not made of cells. A rock is an example of a non-living thing.
You may be wondering whether wood is a "living thing" since it can no longer reproduce once separated from a tree. Think of it like dead skin. It is made of cells, and used to be part of a living thing, but is no longer a growing, breathing organism itself.
