There enough light in the Euphotic zone for photosynthesis. Bathyal zone lacks sunlight. Abyssal zone is cold and dark zone at the bottom. Lacks sunlight yet there are producers at such depth. They are bacteria which can withstand temperatures of 200°C and they produce food through chemical reaction.
