There are 25 elements found in living things. How many of these elements are found in some organisms but not all?
From the tiniest bacteria, to the tallest trees, to the fungi growing on the trees, to every human, to the largest whales, all living things are made of the same materials. These materials can be reduced down to individual elements, different types of atoms that make up the most simple unit of chemistry, which then comprise molecules when combined with other elements. The elements that living things are made of make up a surprisingly small portion of the periodic table. While approximately 25 different elements can be found in any one of these organisms, only six of those are universal in ALL of them and in all life on Earth. Only six! That goes to show us that different combinations of those six elements make all the difference in the vast diversity of cells, tissues, organs, and organisms.
