If what you are asking is; how would one obtain (since you can't make nor destroy energy - first law of thermodynamics) energy if there is no food?
Well, as a human or animal (or any other heterotroph) it is not possible to obtain such energy because unlike plants, we can't take energy from the atmosphere and convert it to usable energy that sustains life.
If one was a photoautotroph or chemoautotroph, then one would be able to convert/obtain energy from sun light or inorganic subtances.
For heterotrophs we need food or else we die.
What else can I help you with?
Plants use energy in what to make food?
Plants use the energy in sunlight to make food
Where do organisms that make their own food get there energy from?
when they make their food and eat it (use it i mean) the producer gets energy. WE get energy by eating, so do they.
What living thing can make food using the sun's energy?
Plants can make food using the sun's energy.
What uses the energy of sunlight carbon dioxide and water to make food?
Chloroplasts use energy of sunlight to make food
Where do mangroves get the energy they need to make their own food?
Energy
What part of your body make energy?
Your body does not make energy, it extracts it from the food you eat.
How do you get the energy your body needs?
You get the energy you need by eating food. Your body makes energy with the nutritions in the food. It can make kinetic energy or potential energy.
What captures suns energy to make food?
Plants capture the sun to make food.
Plants use what to make their own food?
They use photosynthesis to turn sun energy to food energy.
What uses energy to make food?
Chloroplasts convert energy into glucose.
What do the plants do with their energy?
plants perform photosynthesis and make their food with their energy.
What is the organelle that uses energy from food to make energy compounds?
mitochondrion
