Study Notes
Biogeochemical Cycles
- Energy in an ecosystem is not recycled, but matter is.
- Matter cycles between organic and inorganic forms.
- Matter flows between producers, consumers, and decomposers.
- The matter cycles through rocks, water, and the air (geochemical component).
- These are also called biogeochemical cycles.
The Carbon Cycle
- The carbon cycle balances photosynthesis (using carbon) and respiration (forming carbon).
- When organisms die, detritivores and decomposers recycle carbon.
- Burning fossil fuels increases atmospheric carbon dioxide.
- The atmosphere is a reservoir for carbon.

Description
Explore the intricate relationships of matter in ecosystems through biogeochemical cycles, focusing on the carbon cycle's role in balancing photosynthesis and respiration. Understand how matter flows between producers, consumers, and decomposers, and how human activities impact these cycles.
