| Click here for Science Friday Kids' Connection Resource Pages linked to this benchmark. | McREL Benchmark 4. Knows how energy is transferred through food webs in an ecosystem (e.g., energy enters ecosystems as sunlight, and green plants transfer this energy into chemical energy through photosynthesis; this chemical energy is passed from organism to organism; animals get energy from oxidizing their food, releasing some of this energy as heat) (benchmark details) |
