Summary Introduction
Introduction:
Every stage of life is interconnected with each other. Energy is the main source for all ecosystems. Food web or foo clearly explains the linkage of organism in a schematic representation. Based on the use of energy and nutrients, an organism is largely classified into three types: (1) primary producers or autotrophs, (2) consumers or heterotrophs, and (3) decomposers.
