Living organisms are made from compounds of three primary elements: hydrogen, oxygen and carbon - the last giving the term "organic chemistry" to describe now that of any carbon compound even if entirely artificial.
There are also other elements in organisms, depending on the specific Biology, including nitrogen, sulphur, calcium and phosphorous, plus traces of others.

There are several enzymes that are necessary for the metabolism of living organisms. Some of them include bile, pancreatic fluid and carbohydrates.
Carbon
Hydrogen
A bioconstruction is a construction of an architectural element by a group of living organisms.
carbon is the present in all organism.
Sulfur is always happy. It is the 7th most electronegative element. It is necessary for living organisms, and can form dozens of allotropes.

This element is oxygen.

aluminum
It is needed by living organisms.
If you mean element-wise, living organisms contain mostly carbon, oxygen, hydrogen.
Carbon dioxide is a necessary element for the survival of all living things, and it is produced by organisms such as plants and trees. It combines with hydrogen to create oxygen which no living thing can live without.
