Analogue, meaning each object does its own "processing" and produces the appropriate response.
A plant receives light from the sun, performs photosynthesis, captures carbon and releases Oxygen into the atmosphere.
The light from the sun hits the photosynthesis cells in the plant's leaves and a part of that light is absorbed... another part is reflected, some is still refracted.
Absorption of light entails the increase of energy of some electron, or of some atomic or molecular bond.
Reflection happens when the very light wavelength that is absorbed, is also emitted, usually by some electron returning to a lower energetic orbital, but also due to the whole structure's vibration... what we perceive as temperature and can be measured by Infra-red thermography.
Refraction happens when light travels near a corner or slit with a dimension of the order of the wavelength... some photons get scattered, some get through... you get a nice interference pattern.
And this is just a tiny drop of what a plant is doing...
Each electron, each proton, each neutron... is doing its thing.
No one is required to keep them doing their things.
So, to answer your question: no one is governing things on Earth, nor on any other celestial body. The electrons and atoms are working as they do and there's nothing changing that.
