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. It is a key part of the carbon cycle.

What is cellular respiration?

Back

Cellular respiration is the process by which living organisms convert glucose and oxygen into energy, carbon dioxide, and water. It releases carbon back into the atmosphere.

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce CO2 levels and providing oxygen as a byproduct.

How do humans impact the carbon cycle?

Back

Humans impact the carbon cycle through activities like deforestation, burning fossil fuels, and driving cars, which increase carbon dioxide levels in the atmosphere.

What is deforestation?

Back

Deforestation is the clearing of forests, which reduces the number of trees that can absorb carbon dioxide, leading to increased CO2 levels in the atmosphere.

What happens to carbon during decomposition?

Back

During decomposition, dead plants and animals break down, releasing carbon back into the soil and atmosphere, contributing to the carbon cycle.

What is combustion?

Back

Combustion is the process of burning fossil fuels or biomass, which releases carbon dioxide into the atmosphere, contributing to climate change.
