The energy transfer chain is the process by which energy is passed from one organism to another in an ecosystem. It starts with the sun, which provides energy to producers like plants through photosynthesis. These producers are then consumed by primary consumers, which are in turn consumed by secondary consumers, and so on. As organisms eat each other, energy is transferred along the chain, with each organism using some of the energy for its own needs and passing some on to the next organism in the chain. **
