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.
Staphylococcus capitis is an aerobic, Gram-positive, spherical bacterium of the Staphylococcaceae family. The coagulase-negative bacterium belongs to the normal skin flora and is acquired in hospitals in rare cases. Only in humans with weakened immune system Staphylococcus capitis may cause diseases such as endocarditis when entering the body.
