What indicates the unity of living and non-living nature?

The unity of living and inanimate nature is indicated by the elementary chemical composition of the cells of any living organism. The cell contains the same chemical elements that make up inanimate nature.
The difference lies in the percentage of these elements: 98% are carbon, hydrogen, oxygen and nitrogen, they are also called organogenic elements. But macro, micro and ultramicroelements are all the same elements that we can find in the periodic table. This is proof of unity.
