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, involving processes such as photosynthesis, respiration, decomposition, and combustion.

Front

Which process removes carbon dioxide from the atmosphere?

Back

Photosynthesis, primarily carried out by plants, removes carbon dioxide from the atmosphere.

Front

What role do tree farms play in the carbon cycle?

Back

Tree farms absorb carbon dioxide during photosynthesis, helping to reduce atmospheric carbon levels.

Front

True or False: All of the carbon in existence is continually recycled in the carbon cycle.

Back

True.

Front

What happens to organisms that do not decompose?

Back

They can be buried and become fossil fuels over geological time.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, primarily composed of carbon, and include coal, oil, and natural gas.

Front

What gas is produced by plants during photosynthesis?

Back

Oxygen.

Front

Who uses the oxygen produced by plants?

Back

Animals and other organisms use the oxygen produced by plants.

Front

What process returns carbon back into the atmosphere when organisms die?

Back

Decomposition.

Front

What is decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, returning carbon to the atmosphere as carbon dioxide.
