Energy flow can be defined as the unidirectional transfer of solar energy, in the form of organic matters, from producers to the highest level of consumers, through different trophic levels via food chains. Sun is the ultimate source of energy in all ecosystems. Only photosynthetic organisms are capable of trapping and transforming the light energy form the sun into chemical energy in the form of food. This energy is transferred from producers to consumers through food chain, which is called flow of energy.
