the flow is uni directional

Answer 2

$answer$

The flow of energy generally is sun=> herbivores =>carnivores. Since the flow is progressively from one tropic level to another and does not revert back, it is said to be unidirectional. Further the available energy decreases in the higher tropic levels making it impossible for energy to flow in the reverse direction
