Lets look at the definition of nutrients shall we......
A
nutrient is a
chemical that an
organism needs to live and grow or a substance used in an organism's metabolism which must be taken in from its environment.
[1] Nutrients are the substances that enrich the body. They build and repair tissues, give heat and energy, and regulate body processes. Methods for nutrient intake vary, with animals and
protists consuming foods that are digested by an internal digestive system, but most
plants ingest nutrients directly from the
soil through their
roots or from the
atmosphere. An exception are the
carnivorous plants, which externally digest nutrients from animals, before ingesting them. The effects of nutrients are
dose-dependent.
Organic nutrients include
carbohydrates,
fats,
proteins (or their building blocks,
amino acids), and
vitamins. Inorganic chemical compounds such as
dietary minerals,
water, and
oxygen may also be considered nutrients.[

essential to an organism if it cannot be synthesized by the organism in sufficient quantities and must be obtained from an external source. Nutrients needed in large quantities are called
macronutrients;
micronutrients are required in only small quantities.

healthy diet for more information on the role of nutrients in human
nutrition.
So what did we get from that?? No nutrition=No life. Pretty simple to me.
