Key concepts
3 concepts
- 1
The carbon cycle is important because carbon is needed to make all organic molecules, including carbohydrates, lipids, and proteins.
- 2
Photosynthesis removes carbon dioxide from the atmosphere, while respiration, decomposition, and combustion return carbon to the atmosphere.
- 3
Carbon can be stored long-term as fossil fuels, but burning them releases CO₂ into the atmosphere, which can impact Earth's climate.
