Question

Q.2.5. Give scientific reasons:
(1) Energy flow through an ecosystem is 'on
way'.​

Answer 1

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.

Answer 2

Answer:

First of all, it's one way or unidirectional..

Explanation:

When the energy from sunlight is utilised by the plant, much of the energy is lost in the process and as further the food chain increases, the energy gained by the organism is insignificant thus the energy flow through an ecosystem is unidirectional or one way.
