Both seeds may sprout and begin to grow because the parent plant stored some food in the seeds to give them a good start.
But to continue growing, plants need to make more food. Plants do this by photosynthesis. Photosynthesis needs light. No light means no food for the plant.

Assuming the plant has sprouted, in the light, the plant will photosynthesize - that is, it the light intitiates a reaction in the chloroplasts (these are what makes the plant green) to convert carbon dioxide and water into energy for the plant, with oxygen as a biproduct. In the dark, the chloroplasts are unable to function, and most plants then respire - take up oxygen from the atmoshphere and release carbon dioxide.

Google photosynthesis.
Plants use light energy to synthesize food from inorganic sources.
