Ecosystems & the Carbon Cycle; physical science review
Unit 1 Standard: Students will investigate the flow of energy and cycling of matter within an ecosystem and
relate these phenomena to human society.
SEV1a. Interpret biogeochemical cycles including hydrologic, nitrogen, phosphorus, oxygen, and carbon cycles.
Recognize that energy is not recycled in ecosystems.
Main Idea: Matter (water, nitrogen, phosphorus, oxygen, carbon) is cycled (reused by plants & animals) through
ecosystems by chemical reactions and physical changes. Energy is not recycled; it flows and is transferred in
ecosystems according to the Laws of Conservation of Matter and Energy through food webs and food chains.
