Carbon Cycle Review

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, sustaining life on Earth.

Front

What role do fossil fuels play in the carbon cycle?

Back

Fossil fuels release carbon dioxide into the atmosphere when burned, contributing to the greenhouse effect and climate change.

Front

Why is carbon considered the backbone of life?

Back

Carbon is essential for forming the molecules of life, including proteins, lipids, carbohydrates, and nucleic acids.

Front

What is the significance of greenhouse gases?

Back

Greenhouse gases trap heat in the atmosphere, helping to maintain Earth's temperature and support life.

Front

How does photosynthesis relate to the carbon cycle?

Back

During photosynthesis, plants absorb carbon dioxide from the atmosphere and convert it into glucose, which is used for energy and growth.

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 happens to carbon during decomposition?

Back

During decomposition, carbon from dead organisms is released back into the soil and atmosphere, continuing the carbon cycle.

Front

How do oceans contribute to the carbon cycle?

Back

Oceans absorb carbon dioxide from the atmosphere and store it, playing a crucial role in regulating global carbon levels.

Front

What is the impact of deforestation on the carbon cycle?

Back

Deforestation reduces the number of trees that can absorb carbon dioxide, increasing atmospheric carbon levels and contributing to climate change.

Front

What is carbon sequestration?

Back

Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide to mitigate climate change.
