"The energy flow in an ecosystem is unidirectional'. Justify the statement.
✓

Answer

Energy in an ecosystem flows from producers to primary consumers, then from primary consumers to secondary consumers and so on. There is never a back flow of energy, i.e. energy cannot come back to a trophic it has already passed. Therefore, the energy flow is unidirectional in an ecosystem.
