Q. The flow of energy in an ecosystem is
✅ Correct Answer: (C)
Unidirectional
Explanation:
The flow of energy in an ecosystem is unidirectional, meaning energy flows in one direction – from producers (like plants) to consumers (like herbivores and carnivores) and eventually to decomposers. Energy is not recycled; it is lost as heat at each trophic level.
Why other options are incorrect:
- (A) Bidirectional – Energy does not flow back and forth in an ecosystem.
- (B) Circular – While nutrients cycle in an ecosystem, energy flows in a one-way direction.
- (D) Multidirectional – Energy flows in a single direction, not multiple directions.
