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 role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter and releasing oxygen.

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 combustion?

Back

Combustion is a chemical reaction that occurs when a substance (like fossil fuels) reacts with oxygen, producing energy, carbon dioxide, and water.

Front

What are decomposers?

Back

Decomposers are organisms, such as fungi and bacteria, that break down dead organic matter, returning nutrients and carbon to the soil.

Front

How does carbon enter the atmosphere?

Back

Carbon enters the atmosphere through processes like respiration, combustion of fossil fuels, and decomposition of organic matter.

Front

How does carbon get removed from the atmosphere?

Back

Carbon is removed from the atmosphere primarily through photosynthesis, where plants absorb carbon dioxide.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for maintaining the balance of carbon in the environment, supporting life, and regulating climate.

Front

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

Back

Fossil fuels store carbon that was once part of living organisms; when burned, they release carbon dioxide into the atmosphere.
