INFOGRAPHIC 22.4 ENERGY FLOWS UP A FOOD CHAIN
In a food chain, energy flows in one direction: from producers to consumers. Producers obtain energy from the sun. Consumers obtain energy by eating producers. As consumers eat other consumers, the flow of energy continues up the food chain. The passage of energy is not efficient, however, as only 10% of energy makes it from one trophic level to the next. The result is an energy pyramid.
