What are the products of the light reactions of photosynthesis important

The products of the light reactions of the photosynthesis are important because they produce food for the plants, as well as having the oxygen as a waste.

The light is what makes the photosynthesis possible. During this process the plants create sugars, thus making their own food, which enables them to survive and prosper. Since the plants are producers and they are the basis of the ecosystems their survival is crucial for most of the living organisms on the planet. Also, as a waste from this process is released the oxygen. The oxygen is returned into the atmosphere, thus contributing to larger amounts of this crucial gas for the survival of the animals.
