The plants, including the sea grass, are using the light for the process of photosynthesis which is crucial process for their survival as through it they are producing their own food, or rather the sugars. With the light being insufficient or lacking, the sea grass will die out in those parts, and will only be able to exist in the parts where there's enough light.
