Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]
Nutrients are usually the first link in the food chain, thus a loss of nutrients in a habitat will affect nutrient cycling and eventually the entire food chain. [2] [3] Nutrient depletion can refer to shifts in the relative nutrient composition and overall nutrient quantity (i.e. food abundance).

Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
The diet will also result in a nutrition disorder. [4] The diet can also cause choking because the cotton balls cannot be broken down and must be eaten whole. [4] Most "cotton" balls are actually made from bleached polyester rather than cotton, [2] and toxins in the synthetic ingredients of cotton balls can build up over time and cause organ ...
