Flow of energy in an ecosystem is always
unidirectional
bidirectional
multi directional
no specific direction
Answers
Answer:
unidirectional
Explanation:
The flow of energy in the ecosystem is unidirectional because the energy lost as heat from the living organisms of a food chain cannot be reused by plants in photosynthesis. During the transfer of energy through successive trophic levels in an ecosystem, there is a loss of energy all along the path.
Answer:
♠ The correct option is A.
Explanation:
✒️ The flow of energy in the ecosystem is unidirectional. The energy enters the plants (from the sun) through photosynthesis during the making of food. This energy is then passed on from one organism to another in a food chain.
✒️ The energy given out by the organisms as heat is lost to the environment, it does not return to be used by the plants again. This makes the flow of energy in ecosystem 'unidirectional'.
