Give reason
Energy flow in an ecosystem is 'one way'​

Answer 1

In an ecosystem, the energy flow is always unidirectional.

Explanation:

• The energy flows through an ecosystem in one way.
• The energy enters the plants from the sun during photosynthesis.
• The solar energy gets converted to chemical energy in the form of organic compounds by the producers.
• Herbivores, the primary consumers derive their nutrition from one trophic level to the other.
• The energy captured by the producer does not get revert back to the sun.
• Likewise, the energy transferred to the herbivores does not come back to the producers
• The energy just keep moving to one trophic level to the next trophic level in a unidirectional way.
• Hence, the flow of energy in the food chain is always unidirectional or one way.

Answer 2

Answer:

The energy that is obtained by the producers from the sun does not revert to the sun and the energy passed to the herbivores does not return to the producers. the energy always moves to the next trophic level in a unidirectional way. therefore the flow of energy through an ecosystem is one way.
