The correct answer is Minerals.Minerals are a micronutrient.MineralsMinerals are essential for life processes.Human mineral intake represents only about 0.3 % of our total intake of nutrients.Without minerals, we wouldn't be able to use the other 99.7 percent of foods.Plants passively or actively absorb minerals through roots procedures.Important PointsThe essentials of an element for a plant are divided into two broad categories on the basis of their quantitative requirements.MacronutrientsIt is generally present in plant tissues in large amounts (in excess of 10 mmole Kg ‚¬€œ1 of dry matter).The macronutrients are:CarbonHydrogenOxygenNitrogenPhosphorousSulfurPotassiumCalciumMagnesiumMicronutrientsMicronutrients or trace elements are needed in very small amounts (less than 10 mmole Kg ‚¬€œ1 of dry matter).The Micronutrients are:IronManganeseCopperMolybdenumzincBoronChlorineNickel------Additional InformationCarbohydrates??It is an organic compound in which the ratio of Carbon, Hydrogen, and oxygen is 1 : 2 : 1.The general form of carbohydrates is sugar and starch.It is used as fuel for the human body.FatsIt is an ester of glycerol and fatty acid.It provides energy to the body.It remains under the skin and prevents the loss of fat.ProteinsIt is made of 20 types of amino acids.Approximately 16% of the human body is made up of protein.It takes part in the formation of cells, protoplasm, and tissues.
