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, involving processes such as photosynthesis, respiration, decomposition, and fossilization.

Front

What role do trees play in the carbon cycle?

Back

Trees absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce atmospheric CO2 levels.

Front

What is anaerobic respiration and how does it affect the carbon cycle?

Back

Anaerobic respiration is a process by which organisms convert glucose into energy without oxygen, producing carbon dioxide as a byproduct, thus contributing to atmospheric CO2.

Front

How do fossil fuels form in the carbon cycle?

Back

Fossil fuels form from the remains of ancient plants and animals that are subjected to heat and pressure over millions of years, converting biomass into coal, oil, and natural gas.

Front

What is the significance of the aquatic carbon cycle?

Back

The aquatic carbon cycle involves the exchange of carbon between water bodies and the atmosphere, playing a crucial role in regulating global carbon levels and supporting marine life.

Front

What are the main processes involved in the carbon cycle?

Back

The main processes include photosynthesis, respiration, decomposition, combustion, and fossilization.

Front

How do human activities impact the carbon cycle?

Back

Human activities, such as burning fossil fuels and deforestation, increase carbon dioxide levels in the atmosphere, disrupting the natural balance of the carbon cycle.

Front

What is the role of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, releasing carbon back into the atmosphere and soil, thus recycling nutrients and carbon.

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

How does photosynthesis contribute to the carbon cycle?

Back

Photosynthesis allows plants to absorb carbon dioxide from the atmosphere and convert it into glucose and oxygen, thus reducing atmospheric CO2 levels.
