Energy from the sun enters all ecosystems through photosynthesis, is passed through trophic levels (producers, consumers, decomposers) with energy released as heat at every level until all the original energy is eventually released as heat (i.e., Energy Pyramid and 10% Rule).
- Life Science
Energy enters an ecosystem in the form of sunlight and flows through the system to each cell. Matter interacts, changes and recycles in an ecosystem. Populations of organisms survive by maintaining interdependent relationships with one another and by utilizing biotic and abiotic resources from the environment.
Students demonstrate their understanding of Energy Flow in an Ecosystem by
