Correct choice is (a) Unidirectional movement of energy
 
Best explanation: In an ecosystem, a unidirectional flow of energy occurs. The movement of energy from the higher trophic levels and its distribution and loss as heat to the lower trophic levels in the environment is unidirectional. It means the energy moves in one direction only that is from higher to the lower-most level.
