That can be said about basically any process.
When the process energy is transferred, it moves from one object of energy to another. Machines do transfer energy through the process of mechanical work.
diffusion, simple
Convection
That can be said about basically any process.
ocean circulation
it describes a process from one body of energy to another
Radiation
Photosynthesis
Atmospheric circulation sets the energy in the transfer atmosphere in motion
heat transfer
That take place in chlorophylls. Process is called photosynthesis
Energy transfer by convection is primarily restricted to fluids. One of the significant modes of heat transfer is convective heat transfer.
