The producer level has the most available energy in an energy pyramid. It is because producers, such as plants, have the highest amount of energy available from the sun through photosynthesis. As energy flows from one trophic level to the next, some energy is lost in the form of heat or waste, resulting in less energy available to higher levels of consumers. Therefore, each level above the producer level has progressively less energy available.
