Nutrients are components in foods that an organism uses to survive and grow. Macronutrients provide the bulk energy an organism's metabolic system needs to function while micronutrients provide the necessary cofactors for metabolism to be carried out. Both types of nutrients can be acquired from the environment.acronutrients provide the bulk energy an organism's metabolic system needs to function while micronutrients provide the necessary cofactors for metabolism to be carried out.

Staphylococcus epidermidis is a gram-positive, coagulase-negative cocci that is a part of our normal flora. Consequently, it is a true opportunistic pathogen, as it requires a major breach in the hostâs innate defenses.
The natural environment of S. epidermidis is the human body and usually originates from disease. Since the bacteria usually lives on the skin and nares of all human beings and is a nosocomial pathogen, it is imporant to be able to identify the specific strains.S. epidermidis is the most common staphylococcus on the human skin.In addition, S. epidermidis also covers 90%-100% staphylococci from the nares when S. aureus is not present. When S. aureus is present the S. epidermidis amount decreases drastically (4).he natural environment of S. epidermidis is the human body and usually originates from disease.
