Carbon Cycle

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, decomposition, and combustion.

Front

What process do plants use to take in carbon dioxide?

Back

Photosynthesis.

Front

What is produced by plants during photosynthesis?

Back

Glucose (sugar) and oxygen.

Front

What happens to carbon when animals decompose?

Back

It increases the amount of carbon in the soil.

Front

What is combustion?

Back

Combustion is a chemical process where substances combine with oxygen to release energy, often producing carbon dioxide and water.

Front

Where does carbon go when fossil fuels are burned?

Back

Most of the carbon quickly enters the atmosphere as carbon dioxide.

Front

What is respiration in the context of the carbon cycle?

Back

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

Front

What role do decomposers play in the carbon cycle?

Back

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

Front

What is the significance of photosynthesis in the carbon cycle?

Back

Photosynthesis removes carbon dioxide from the atmosphere and converts it into organic matter, which is essential for life.

Front

What is the main greenhouse gas produced by burning fossil fuels?

Back

Carbon dioxide (CO2).
