Energy flow in ecosystems
Biology · Secondary 4 · Medium · Energy flow in ecosystems
A student states that energy in an ecosystem is recycled just like water. Which statement correctly applies the idea of energy flow to show why this is wrong?
- Energy is lost as heat at each trophic level and is not returned to the Sun, so it flows one way only.
- Energy is destroyed during photosynthesis so it cannot be recycled.
- Energy is stored only in decomposers and never leaves the soil.
- Energy cycles only between producers and consumers but not decomposers.
