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.

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?

Back

Respiration is the process that takes in glucose and water and yields carbon dioxide and water, releasing energy.

Front

What is combustion?

Back

Combustion is the rapid chemical combination of a substance with oxygen, producing heat, light, and carbon dioxide.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen.

Front

What role do animals play in the carbon cycle?

Back

Animals contribute to the carbon cycle through respiration, which releases carbon dioxide back into the atmosphere.

Front

What is limestone?

Back

Limestone is a sedimentary rock that is part of the geosphere and is composed mainly of calcium carbonate.

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that helps regulate Earth's temperature and is essential for photosynthesis.

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.

Front

How does combustion affect the carbon cycle?

Back

Combustion releases carbon dioxide into the atmosphere, increasing the amount of carbon available in the cycle.
