===Light helps the ecosyetem and population because it gives off energy which feed the other organisms. But if you were to take this factor out then the whole ecosystem would fall apart and become extinct. Light feeds the producers through photosynthesis. The first level consumer feeds off of the producers, the second-level consumers feed off of the third-level consumer, and the fourth-level consumer feeds off of the third-level consumer. So if the producers died it would be a domino effect. Light affects the ecosystem, so if there was no light there would be no ecosystem. ===
