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 role do oceans play in the carbon cycle?

Back

Oceans absorb carbon dioxide from the atmosphere and are home to marine organisms that use carbonic acid to form shells, thus playing a crucial role in the carbon cycle.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, 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, including animals and plants, take in oxygen and release carbon dioxide as a byproduct of converting glucose into energy.

Front

What is combustion?

Back

Combustion is the process of burning fossil fuels or biomass, which releases carbon dioxide and other gases into the atmosphere.

Front

What is decay in the carbon cycle?

Back

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

Front

Why is carbon important for the atmosphere?

Back

Carbon is essential for maintaining the Earth's temperature by trapping heat in the atmosphere, a phenomenon known as the greenhouse effect.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases, including carbon dioxide.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce atmospheric carbon levels.

Front

What happens to carbon during decomposition?

Back

During decomposition, carbon from dead organisms is released back into the soil and atmosphere, where it can be reused by plants.
