Sunlight can be considered a food resource.

I think this is partly true and partly false. It is partly true because plants undergo in a process called photosynthesis and it is sunlight that makes them do this. It is partly not true because literally the sunlight can't be considered a food source because it actually don't give you food.

This is incorrect. Sunlight is a form of energy that can be utilised, for example by plants, to produce a food source during the process of photosynthesis. In this example, photosynthesis uses sunlight, carbon dioxide and water to produce glucose (food).
