WebNutrient cycling. The cells of all organisms are made up primarily of six major elements that occur in similar proportions in all life-forms. These elements— hydrogen, oxygen, carbon, nitrogen, phosphorus, and sulfur —form the core protoplasm of organisms, and the first four of these elements make up about 99 percent of the mass of most cells.
