Question

energy flow through an ecosystem in one way write scientific reason
​

Answer 1

Explanation:

energy flow through an ecosystem is one way, because when the energy enters the plants (from the sun) during photosynthesis. This energy is then passed on from one organism to another in a food chain but it does not come back. Thus energy flow in an ecosystem is unindirectional.

Answer 2

Answer:

energy flow through an ecosystem is one way, because when the energy enters the plants (from the sun) during photosynthesis. This energy is then passed on from one organism to another in a food chain but it does not come back. Thus energy flow in an ecosystem is unindirectional.

So, the energy that is captured by the producers does not revert back to the Sun and the energy transferred to the herbivores does not come back to the producers. It just keeps on moving to the next trophic level in a unidirectional way. That is why the flow of energy in the food chain is always unidirectional/one way.
