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 like photosynthesis, respiration, decomposition, and combustion.

Front

What do plants depend on for photosynthesis?

Back

Plants depend on carbon dioxide, sunlight, and water to perform photosynthesis, which allows them to produce glucose and oxygen.

Front

What gas do humans depend on for survival?

Back

Humans depend on oxygen for survival, which is produced by plants during photosynthesis.

Front

What is combustion?

Back

Combustion is a chemical reaction that involves the burning of substances, typically in the presence of oxygen, resulting in the release of energy, carbon dioxide, and water.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen, thus playing a crucial role in regulating atmospheric carbon levels.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms, including humans and animals, consume oxygen and release carbon dioxide as a byproduct.

Front

What is the significance of decomposition in the carbon cycle?

Back

Decomposition is the process by which dead organic matter is broken down by decomposers, returning carbon to the soil and atmosphere, thus continuing the carbon cycle.

Front

How do fossil fuels relate to the carbon cycle?

Back

Fossil fuels, such as coal, oil, and natural gas, are formed from ancient organic matter and release carbon dioxide into the atmosphere when burned, impacting the carbon cycle.

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 the relationship between carbon dioxide and global warming?

Back

Increased levels of carbon dioxide in the atmosphere contribute to the greenhouse effect, leading to global warming and climate change.
