Carbon Cycle Review

Front

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 processes like photosynthesis, respiration, decomposition, and combustion.

Front

What are carbon molecules?

Back

Carbon molecules are compounds that contain carbon atoms. Examples include carbon dioxide (CO2), glucose (C6H12O6), and carbon monoxide (CO). Oxygen (O2) is NOT a carbon molecule.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide (CO2) from the atmosphere during photosynthesis, converting it into glucose and oxygen.

Front

What role do animals play in the carbon cycle?

Back

Animals obtain carbon by consuming plants and other animals, and they release carbon dioxide (CO2) back into the atmosphere through respiration.

Front

What is the impact of burning fossil fuels on the carbon cycle?

Back

Burning fossil fuels releases large amounts of CO2 into the atmosphere, contributing to global warming and disrupting the natural balance of the carbon cycle.

Front

What is deforestation and how does it affect the carbon cycle?

Back

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

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide (CO2) 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 convert glucose and oxygen into energy, releasing carbon dioxide (CO2) as a byproduct.

Front

What is decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, releasing carbon back into the soil and atmosphere.

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 like CO2, which are released through human activities.
