No, see as the unicellular organism digest the food it turns it into energy,
The chemical energy that an organism obtains from food is converted to ATP.
Energy is transferred through a food chain when an organism eats another organism. As the food chain progresses, less energy is available when an organism is consumed.
Energy flows from one organism to another.One organism eats other organism and energy is transferred.
Chemical
the answer you are most likely looking for is any photosynthetic plant.
A biologist would most likely study all the chemical activities of an organism to obtain information about the organisms metabolism. The organism gets energy from food through metabolism because the body's cells convert food into the energy needed to do everything from moving to thinking to growing.
Energy and nutrients are passed from organism to organism, through the food chain as one organism, eats another.
Unless your doing a degree course this sounds most likely to be respiration.
How energy moves from organism to organism.
A food store is needed for developing young organism, once its fertilised.
when an organism uses most of it's carbohydrates, it can get energy from these lipids
