I am not sure I completely understand your question, but you seem to be referring to "micronutrients" which encompasses both vitamins and minerals. These, by definition, are essential for sustaining life but are needed in only very small daily quantities. In contrast the "macronutrients" (protein, fat, carbs) are needed in much larger quantities to provide us with our caloric needs for energy.
