Inorganic nutrients that facilitate growth and development in organisms include phosphorous, calcium, nitrogen, iron and fluorine. There are many different kinds of inorganic nutrients, and they are all characterized by their lack of carbon-to-carbon bonds.
There are six classes of nutrients, which include carbohydrates, lipids, proteins, vitamins, minerals and water. The nutrients that contain carbon in their structural makeup are referred to as organic nutrients, whereas those that do not contain carbon are called inorganic nutrients. Therefore, the organic nutrients are carbohydrates, lipids, proteins and vitamins. These nutrients are important for energy.
