Question

The flow of energy in an ecosystem is:

• A. Unidirectional
• B. Bidirectional
• C. Multidirectional
• D. Cyclic

Hint:

Matter cycles in ecosystem, but energy flows in a single direction and eventually dissipates as heat.

Answer 1

The Correct Option is A

Step 1: Recall.
Energy enters the ecosystem through sunlight (producers) and flows to herbivores, carnivores, and decomposers.
Step 2: Concept.
Unlike matter, energy cannot be recycled. It flows in one direction only.
Step 3: Conclusion.
Thus, energy flow in an ecosystem is unidirectional.
