Question

Flow of energy in an ecosystem is always

• A. Unidirectional
• B. Bidirectional
• C. Multi directional
• D. No specific direction

Answer 1

The correct option is A

Unidirectional

Flow of energy in an ecosystem is unidirectional. Plants absorb energy from the Sun and convert it into food, herbivores eat plants and energy transfer takes place. Carnivores eat herbivores and the energy gets transferred, the vice versa never takes place.
