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 process removes carbon dioxide from the atmosphere?

Back

Photosynthesis is the process that removes carbon dioxide from the atmosphere, as plants convert CO2 into glucose and oxygen.

Front

What is the role of respiration in 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 human activities contribute to increased carbon dioxide levels?

Back

Burning fossil fuels, deforestation, and industrial processes are human activities that contribute to increased carbon dioxide levels in the atmosphere.

Front

What is the significance of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus playing a crucial role in recycling carbon.

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, including carbon dioxide.

Front

How do oceans contribute to the carbon cycle?

Back

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

Front

What is the difference between carbon sinks and carbon sources?

Back

Carbon sinks are natural systems that absorb more carbon than they release (e.g., forests, oceans), while carbon sources release more carbon than they absorb (e.g., fossil fuel combustion).

Front

What is the impact of deforestation on the carbon cycle?

Back

Deforestation reduces the number of trees available to absorb carbon dioxide, increasing atmospheric CO2 levels and contributing to climate change.

Front

What is combustion in the context of the carbon cycle?

Back

Combustion is the process of burning organic materials, which releases carbon dioxide and other greenhouse gases into the atmosphere.
