HUMAN NUTRITION

Detailed explanation-1: -The only nutrients that are inorganic in nature are water and minerals. The presence or absence of carbon is what differentiates organic nutrients from inorganic nutrients. Carbohydrates, lipids, proteins and vitamins have carbon in their structure, making them organic. Water and minerals do not, so they are inorganic.

Detailed explanation-2: -Calcium is an inorganic mineral nutrient. It is an essential macronutrient.

Detailed explanation-3: -Nutrients may be organic or inorganic: organic compounds include most compounds containing carbon, while all other chemicals are inorganic. Inorganic nutrients include nutrients such as iron, selenium, and zinc, while organic nutrients include, among many others, energy-providing compounds and vitamins.

Detailed explanation-4: -Minerals are inorganic elements present in soil and water, which are absorbed by plants or consumed by animals.
