Carbon Cycle

Front

What happens to carbon dioxide levels if the plant population decreases?

Back

The amount of carbon dioxide in the atmosphere would increase.

Front

What is another term for combustion?

Back

Burning.

Front

Where does all the carbon in living organisms originate from?

Back

They can be buried and become fossil fuels.

Front

Define the carbon cycle.

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis, reducing atmospheric CO2 levels.

Front

What is the significance of fossil fuels in the carbon cycle?

Back

Fossil fuels store carbon that was once part of living organisms, releasing CO2 when burned.

Front

How do oceans act as a carbon sink?

Back

Oceans absorb carbon dioxide from the atmosphere, helping to regulate global carbon levels.

Front

What is respiration in the context of the carbon cycle?

Back

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