Classification of organism based on Nutritional requirements Carbon →Autotrophs. -> He-torotrophs. Energy phototrophs Chemotrophs. Hydrogen/electrons Lithotrophs (organism can extract &s from Inorganic substance). Organotrophs (organism can extract is from. Organic substursce). Major Nutritional types of Microorganisms.
