Summary Introduction
Introduction: According to the nature of food creation and consumption, the organisms are basically classified into two groups, such as autotrophs and heterotrophs. The autotrophs are the organisms that can synthesize their own food from simple molecules using water and carbon dioxide in the presence of sunlight and chlorophyll. The heterotrophic organism is unable to synthesize their own food and depends on other living organisms to obtain food.
