Notes:
The energy enters the plants from the sun through the photosynthesis process. This energy is then passed on from one organism to another in a food chain. The flow of energy in the ecosystem is unidirectional because the energy lost as heat from the living organisms of a food chain cannot be reused by plants in photosynthesis. During the transfer of energy through successive trophic levels in an ecosystem, there is a loss of energy all along the path.
