Nutrition Photosynthesis, Inorganic Salts, Fertilizers, and

OverviewNutrition in bacteriaNutrition in animalsPlants, unlike animals, do not have to obtain organic materials for their nutrition, although these ) and water. However, plants do require inorganic salts, which they absorb from the soil surrounding their roots; these include the elements phosphorus (in the form of phosphate), chlorine (as the chloride ion), potassium, sulfur, calcium, magnesium, iron, manganese, boron, +) ions. They will, in addition, take up inorganic compounds that they themselves do not need, sThe nutrients found in soil result in part from the gradual breakdown of the rocky material on Earth ’s surface as a result of rain and, in some areas, freezing. Primarily composed of alumina and silica, rocks also contain smaller amounts of all the mineral elements needed by plants. Anothe在britannica上查看更多信息
