The Carbon Cycle Flashcard

Front

What is the process by which carbon is returned to the atmosphere as carbon dioxide?

Back

Respiration is the process by which carbon is returned to the atmosphere as carbon dioxide.

Front

What is the main source of carbon for plants during photosynthesis?

Back

The main source of carbon for plants during photosynthesis is carbon dioxide.

Front

Which kind of organisms are decomposers?

Back

Decomposers are primarily bacteria and fungi.

Front

During photosynthesis, what gas is released into the atmosphere?

Back

Oxygen is released into the atmosphere during photosynthesis.

Front

What is the breakdown of dead organisms and waste materials called?

Back

The breakdown of dead organisms and waste materials is called decomposition.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce atmospheric carbon levels.

Front

What is the significance of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus recycling nutrients.

Front

How does combustion affect the carbon cycle?

Back

Combustion releases carbon dioxide into the atmosphere, increasing greenhouse gas levels and impacting climate change.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to trapped heat from greenhouse gases like carbon dioxide.
