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 and some other organisms use sunlight to synthesize foods with the help of carbon dioxide and water, releasing oxygen as a byproduct.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce carbon levels and store carbon in their biomass.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light, and releasing carbon dioxide and other gases into the atmosphere.

Front

How do decomposers contribute to the carbon cycle?

Back

Decomposers break down dead organic matter, releasing carbon dioxide back into the atmosphere through the process of decomposition and cellular respiration.

Front

What happens to carbon dioxide levels when trees are cut down?

Back

When trees are cut down, carbon dioxide levels in the atmosphere increase because the carbon stored in the trees is released during decomposition or combustion.

Front

What is the impact of vehicle emissions on the carbon cycle?

Back

Vehicle emissions release carbon dioxide and other greenhouse gases into the atmosphere, contributing to climate change and altering the natural carbon cycle.

Front

What is ocean uptake in the context of the carbon cycle?

Back

Ocean uptake refers to the process by which oceans absorb carbon dioxide from the atmosphere, helping to regulate global carbon levels.

Front

What is the significance of carbon sinks?

Back

Carbon sinks are natural systems, like forests and oceans, that absorb more carbon than they release, helping to mitigate climate change by reducing atmospheric carbon dioxide.
