HUMAN NUTRITION

Detailed explanation-1: -In relatively large amounts, the soil supplies nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur; these are often called the macronutrients. In relatively small amounts, the soil supplies iron, manganese, boron, molybdenum, copper, zinc, chlorine, and cobalt, the so-called micronutrients.

Detailed explanation-2: -Minerals, such as calcium and iron, come from the earth or environment. Minerals do not contain carbon, meaning they are inorganic compounds. Nutrients accumulate, or build up, in the environment. Nutrient-rich soil or water contains large amounts of nitrogen, carbon, phosphorus, sulfur, and potassium.

Detailed explanation-3: -Micronutrients are the nutrients that are required by plants in small amounts or quantities. E.g., Zinc, iron, copper, manganese, molybdenum, etc.
