Match the stages of the carbon cycle to the correct description:

Photosynthesis = Carbon is removed from the atmosphere and stored in glucose. Decomposition = Carbon is released back into the atmosphere. Formation of fossil fuels = Carbon is stored in dead organisms for millions of years. Respiration = Carbon is released back into the atmosphere. Signup and view all the answers

Study Notes

The Carbon Cycle

Removing Carbon Dioxide from the Atmosphere

Photosynthesis equation: CO2 + water → glucose + O2
Examples of organisms that photosynthesize:
Two ways carbon is removed from the atmosphere:
- Photosynthesis by organisms
- Formation of carbonates in shells and bones of marine organisms

Transfer of Carbon

Carbon is transferred between different carbon reservoirs:
- Through the food chain (e.g., when animals eat plants)
- When organisms die and carbon remains in fossil fuels
- When plants and animals respire, releasing CO2

Releasing Carbon Dioxide into the Atmosphere

Stages of the carbon cycle where CO2 is released:
- Respiration by plants and animals
- Combustion of fossil fuels
- Decomposition of waste material and dead organisms
