Additionally, living things also contain water, which is crucial for maintaining life processes.
Nonliving THINGS do not contain cells, however ALL THINGS, whether living or non-living, do contain atoms.

Yes. All living things contain nitrogen.
All living things contain cells, which are the basic building blocks of life. These cells contain genetic material, such as DNA, that carries instructions for how the organism functions. Living things also contain proteins, which are essential for carrying out various biological processes.
Yes, all living things contain carbon.
Carbon
No, not all living things contain cells. Viruses, for example, are considered living but are not made up of cells. They are instead composed of genetic material encased in a protein coat.
No, not all living things contain sodium. Sodium is an essential mineral needed by most living organisms for various physiological functions, but there are living things such as certain freshwater organisms or extremophiles that can survive in environments with very low or no sodium levels.
