NCES.6.L.2 - Understand the flow of energy through ecosystems and the responses of populations to the biotic and abiotic factors in their environment.
- NCES.6.L.2.1 - Summarize how energy derived from the sun is used by plants to produce sugars (photosynthesis) and is transferred within food chains and food webs (terrestrial and aquatic) from producers to consumers to decomposers.
- NCES.6.L.2.2 - Explain how plants respond to external stimuli (including dormancy and forms of tropism) to enhance survival in an environment.
- NCES.6.L.2.3 - Summarize how the abiotic factors (such as temperature, water, sunlight, and soil quality) of biomes (freshwater, marine, forest, grasslands, desert, Tundra) affect the ability of organisms to grow, survive and/or create their own food through photosynthesis.
