The correct answer is (a) Flow is unidirectional
 
Best explanation: The statement “The energy passed from producers to consumers (herbivores) does not go back to producers (autotrophs)” tells that the flow of energy is unidirectional. It means the energy moves in one direction only that is from higher to the lower-most level.
