It shows permissible power dissipation as a function of ambient temperature. For example, some power could be in the form of electromagnetic radiation such as radio waves or light.
Yes, in this case all power dissipated will be in the form of heat. The graph is not showing how much power the diode will dissipate as a function of temperature. Watts that “go through” the diode won’t affect it as they’ll get to the load.
This chart is means to aid in thermal design, to know where to place or not to place the diode on the board, and to figure out what size of heat sink you need. The latter parameter covers the thermal resistance of the chip to case, case to heatsink if provided and datashert to air or coolant. No, it shows how much power the diode by itself can dissipate at different temperatures.

You appear to have written two sentences but separated them by a comma so it’s not clear what you are saying. If it’s hot dagasheet around, less power will get something to a particular temperature than when it’s cold all around.

FR107 – FR107 1000V 1A Fast Recovery Diode
According to this chart of a diode’s power dissipation over temperature, the power dissipation would decrease as temperature goes up. I didn’t use the expression, “The power to be dissipated” so I don’t understand why you are quoting it back to me.

Remember that temperature of the device rises until the power lost to cooling equals the electrical power input. Only if that is absorbed by something will it be converted to and that at the point of absorption not at the source. In other cases it might not as explained above. Watts dissipated at the datasjeet are the problem.
