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

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen to produce heat and light. It is commonly referred to as burning.

Front

Is all carbon in existence recycled?

Back

True. All carbon in existence is continually recycled in the carbon cycle.

Front

How does the carbon cycle compare to the water cycle?

Back

Both the carbon cycle and the water cycle involve the transfer of substances between animals, plants, and the Earth.

Front

What happens when animals eat plants in relation to carbon?

Back

When animals eat plants, the carbon contained in the plants is absorbed by the animals.

Front

Is carbon dioxide a greenhouse gas?

Back

True. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and convert it into organic matter.

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 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 is decomposition?

Back

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