Energy in an ecosystem is recycled is reused flows only one way is returned to the soil through decomposition

Energy in an ecosystem is returned to the soil through decomposition

Explanation:

Energy is maintained in an ecosystem by cycling nutrients and energy received from external sources.

There is chain through which energy is maintained in the ecosystem.

Firstly energy is consumed by plants from sun in the form of solar energy, then it is eaten by herbivore and again herbivore is either eaten by carnivore or omnivore and when they are dead and decayed and it would decomposed by bacteria and nutrients get entered into soil.

So, last energy is returned to the soil through decomposers.

Hence, fourth option is correct.
