Answer: Energy is released
Explanation:
Organic molecules has the ability to decompose and release energy in the ecosystem. Energy can neither be created nor be destroyed, it can only be converted from one form to another form.
The organic molecules have energy stored in them, this energy is released when the organic matter is decomposed, it gets into the form of nutrients in soil.
This nutrient is used by plants and this is how the organic molecules transform energy from one form to another.
