Question

energy flows on ecosystem is one way​

Answer 1

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 not directional.

Answer 2

Answer:

1. The sun is the most important source of energy in an ecosystem.
2. Green plants of the ecosystem store some of the solar energy in the form of food.
3. Before reaching the decomposers, This energy is passed on form on trophic level to the next.
4. Decomposers dissipate some amount of energy in the form of heat
5. However, no part of energy ever returns to the sun.
6. Hence, energy flow through an ecosystem is 'One way'.
