The term 'DAYLIGHT PROVIDER' can be solved by the three letter word 'SUN'. The SUN is a star that is located at the center of our solar system and is the primary source of energy for life on Earth. It provides light and heat to the planet, and its energy is responsible for the growth of plants and other organisms. The SUN's light is also responsible for the day-night cycle, which is why it is referred to as a daylight provider.
