CARBON CYCLE

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. It involves processes such as photosynthesis, respiration, decomposition, and combustion.

What happens when forests are cleared or burned?

Back

When forests are cleared or burned, stored carbon dioxide is released into the atmosphere, contributing to the greenhouse effect and impacting the carbon cycle.

Front

How does transportation affect atmospheric carbon dioxide levels?

Back

Transportation increases the amount of atmospheric carbon dioxide due to the burning of fossil fuels, which releases CO2 as a byproduct.

Front

What is the impact of rapid expansion of farming on carbon dioxide levels?

Back

The rapid expansion of farming increases atmospheric carbon dioxide levels, primarily through deforestation and the use of machinery that emits CO2.

Front

How does carbon dioxide contribute to global warming?

Back

Carbon dioxide traps heat in the lower atmosphere, leading to an increase in global temperatures, which affects the carbon cycle.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter and releasing oxygen.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide 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 back into the atmosphere.

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 combustion?

Back

Combustion is the process of burning fossil fuels or biomass, which releases carbon dioxide and other greenhouse gases into the atmosphere.
