Without sunlight, plants could not produce their own energy, therefore they could not resist to this environment condition and die. That way, the herbivores could not feed and die as well. Also the carnivore could not survive because their supply of food of herbivores are not alive anymore. This scenario would promote a mass extinction of every dinosaur.
