Nutrition is the process by which living organisms take their food for maintaining proper growth, metabolisms and replacement of tissue. Plants nutrition occurs in two phases such as synthesis and assimilation. Generally, plants nutrition is of two types such as autotrophic plant nutrition and heterotrophic nutrition.Autotrophic Plant NutritionIn autotrophic nutrition, the plant gains simple

For an element to be considered an essential nutrient, it must meet the following three criteria (1) The element must be necessary for normal plant development through a complete life cycle; (2) no other element can substitute for that element; and (3) the element must play a role in metabolism within the plant. . Studies to demonstrate whether an element is essential are often very difficult

The many needs for nitrogen in plant cells make nitrogen assimilation a significant part of overall plant cell metabolism. The form of nitrogen most often available to plants in soil is nitrate ion (NO 3-). This is because soil bacteria tend to oxidize more reduced forms of nitrogen to gain electrons for their energy metabolism.

By the same token, in calcium metabolism, if you're eating a moderate amount of calcium, getting adequate vitamin D intake or sun exposure and not ingesting much sodium or any animal protein, your kidneys will not be dumping any calcium so the calcium you eat is the calcium that gets banked in the form of density.
