The energy exchange that occurs between organisms at different trophic levels is referred to as trophic transfer or energy flow. Producers, such as plants, convert solar energy into chemical energy through photosynthesis. Primary consumers, or herbivores, feed on these producers, and secondary consumers prey on primary consumers, passing energy up the food chain. Only about 10% of the energy at one trophic level is transferred to the next, illustrating the concept of energy efficiency and highlighting the importance of understanding these dynamics for ecosystem management.
