Step-by-step solution

Autotrophic nutrition involves the manufacture of organic materials from inorganic raw materials with the help of energy obtained from outside sources. It is of two types chemosynthesis and photosynthesis. Chemosynthetic: The organisms which are able to manufacture their organic food from inorganic raw materials with the help of energy derived from exergonic chemical reactions are called chemoautotrophs. Nitrosomonas and Nitrobacter are chemoautotrophic nitrifying bacteria. Photosynthetic: Those organisms who can m
