What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms. It involves various processes such as photosynthesis, respiration, decomposition, and combustion.

What happens when humans burn fossil fuels?

Back

When humans burn fossil fuels, carbon is released into the atmosphere as carbon dioxide, contributing to climate change.

Front

What process removes carbon dioxide from the atmosphere?

Back

Photosynthesis removes carbon dioxide from the atmosphere as plants convert it into glucose using sunlight.

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 role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere through decomposition.

Front

How does photosynthesis contribute to the carbon cycle?

Back

Photosynthesis allows plants to absorb carbon dioxide from the atmosphere and convert it into organic matter, thus reducing atmospheric carbon levels.

Front

What is the impact of warmer temperatures on the carbon cycle?

Back

Warmer temperatures can increase the frequency of wildfires and 'zombie fires', which release stored carbon back into the atmosphere.

Front

What is combustion?

Back

Combustion is a chemical process that involves burning fossil fuels, which releases carbon dioxide and other greenhouse gases into the atmosphere.

Front

What is the difference between photosynthesis and respiration?

Back

Photosynthesis removes carbon dioxide from the atmosphere to produce glucose, while respiration releases carbon dioxide back into the atmosphere as organisms convert glucose into energy.

What is the significance of the carbon cycle for life on Earth?

Back

The carbon cycle is essential for regulating Earth's climate, supporting plant growth, and maintaining the balance of carbon in the environment.
