true, living things do use food as their source of energy to carry out their live functions. But foodcan be a various amount of thing such as sunlight, rotten flesh, algae and tons more.
The biosphere contains all of Earth's living things.
Last I heard, the energy molecule for humans is ATP, adenosine triphosphate. I don't think that other living things such as plants have ATP. They do photosynthesis. But regarding humans, ATP is taught to be the energy molecule.
Many living things can be traced back to sunlight because plants uses sunlight for energy, animals eats that plant getting that energy, than a human eats that animal getting all the energy.
