Sunlight is needed for the light cycle, but ATP created by the electron transport chain is needed for the dark cycle, the cycle that creates sugars.
They need it as energy for their bodies. They take sunlight and oxygen to do photosynthesis, and then get ATP, (energy in a form that plants can use) to live, and flourish. Without it, they'd die.
it gives us energy
It oxidizes sugars to convert chemical bonds to energy.
Energy.
When energy is used to make sugars, it is called photosynthesis. This process occurs primarily in plants, algae, and some bacteria, where they convert light energy, usually from the sun, into chemical energy stored in glucose. During photosynthesis, carbon dioxide and water are transformed into sugars and oxygen, using sunlight as the energy source.
