The transfer of energy in a food chain is always
- Bidirectional
- Same directional
- Unidirectional
- Cyclic
Hint:
The transfer of energy in a food chain is always unidirectional.
The correct answer is: Unidirectional
- A food chain always follows a progressing straight path and is always straight.
- Due to the fact that the sun is the only energy source for all terrestrial ecosystems, the energy flow in the food chain is unidirectional.
- Energy flow is the systematic, sequential movement of energy from producers to decomposers at different trophic levels.
