How 10 percent law is associated with flow of energy?

Food chains show how energy moves through an ecosystem, the combined physical and biological elements in an environment. In a food chain, producers, organisms that make their own food, provide food for animals called first-level consumers. These animals are then eaten by second-level consumers, which may be consumed by third-level consumers. Scientists estimate that only 10 percent of the producers' energy is passed to the first-level consumer.
