Answer :
Final answer:
Energy in ecosystems is utilized by organisms and lost as heat. Trophic levels show energy transfer, and ecological efficiency impacts energy flow.
Explanation:
Energy in ecosystems follows a path where it is used by organisms and eventually lost as heat into the environment. Energy flow through trophic levels demonstrates that each level receives only a fraction of the energy from the previous level. Ecological efficiency plays a crucial role in how much energy is transferred between trophic levels.
