Summary Introduction
Introduction: According to the energy consumption pathway, organisms are splinted up into autotrophs and heterotrophs. Autotrophs are organisms that convert simple substances from the environment into complex organic compounds by using light energy in the process of photosynthesis. Heterotrophs are organisms that can’t synthesize their own food; they imbibe or obtains their food and energy from plant or animal matters.
