Front

What part of the carbon cycle occurs when plants or fossil fuels are burned?

Back

Combustion

Front

What process takes carbon dioxide out of the atmosphere?

Back

Photosynthesis

Front

What is the role of photosynthesis in the carbon cycle?

Back

Photosynthesis converts carbon dioxide into oxygen and glucose, removing carbon from the atmosphere.

Front

What is combustion in the context of the carbon cycle?

Back

Combustion is the process of burning fossil fuels or biomass, releasing carbon dioxide into the atmosphere.

Front

How does respiration contribute to the carbon cycle?

Back

Respiration is the process by which living organisms convert oxygen and glucose into energy, releasing carbon dioxide.

Front

What is decomposition and its role in the carbon cycle?

Back

Decomposition is the breakdown of dead organic matter, returning carbon to the soil and atmosphere.

Front

What are fossil fuels and their significance in the carbon cycle?

Back

Fossil fuels are natural substances formed from ancient organic matter, and their combustion releases significant amounts of carbon dioxide.
