Flashcards
What is the carbon cycle?
What is the carbon cycle?
The continuous movement of carbon through ecosystems.
How does energy differ from matter in an ecosystem?
How does energy differ from matter in an ecosystem?
Energy flows in one direction through ecosystems, but matter is recycled.
What does it mean that the carbon cycle is biogeochemical?
What does it mean that the carbon cycle is biogeochemical?

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.
