Like all human beings plants also need some essential nutrients to grow. Plants usually take nutrition in the form of inorganic materials. A plant usually gets energy from photosynthesis and nutrition from the soil. From soil, nutrition can be given by the interaction of various steps and finally it provides nutrients to plants to grow. In-plant nutrition many chemical pathways are needed to be undergone to yield nutrition. Plants also need micro and macro nutrients to grow without any diseases. Plant growth management can be calculated or can be estimated with the help of chemical reactions which takes place in the nutrition formation from the soil as inorganic materials. Animal nutrition highly focuses on the dietary requirements which are essential for the growth and maintenance of animals. Like humans animals also need nutrition in the specific ration. Based on the nutrition intake and mode of food preparation animals can be classified into groups. Autotrophs and heterotrophs are the two major classes based on the mode of food intake. Animals need fatty acids in a small amount since most of the fatty acids can be secreted from their own bodies. Carbohydrates, proteins, fats are the other essential nutrients required by animals.
