Carbon Cycle and Human Impact

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.

Front

How do animals release carbon back into the carbon cycle?

Back

Animals release carbon back into the carbon cycle through respiration and decomposition.

Front

What process absorbs carbon from the atmosphere?

Back

Photosynthesis absorbs carbon from the atmosphere by converting carbon dioxide into glucose using sunlight.

Front

What is a natural source of CO2?

Back

Methane is a natural source of CO2, as it can be converted into carbon dioxide through oxidation.

Front

How do humans release carbon into the atmosphere?

Back

Humans release carbon into the atmosphere primarily through cellular respiration and combustion of fossil fuels.

Front

What is the lithosphere?

Back

The lithosphere is the reservoir of carbon made up of the ground, including soil, rocks, fossil fuels, and other geological formations.

Front

What role do plants play in the carbon cycle?

Back

Plants play a crucial role in the carbon cycle by absorbing carbon dioxide during photosynthesis and releasing oxygen.

Front

What is decomposition in the context of the carbon cycle?

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 a chemical reaction that occurs when carbon-based materials are burned, releasing carbon dioxide into the atmosphere.

Front

What is respiration?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide as a byproduct.
