Answer: 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.

Both also contain similar membranes, cytosol, and cytoskeletal elements.
