Carbon Cycle

Front

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 role do decomposers play in the Carbon Cycle?

Back

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

Front

What is carbon dioxide (CO2)?

Back

Carbon dioxide (CO2) is a colorless, odorless gas that is a significant greenhouse gas and is produced by respiration, combustion, and decomposition.

Front

Where can carbon be found?

Back

Carbon can be found in the atmosphere, soil, fossil fuels, and living organisms.

Front

What is the greatest contributor to atmospheric carbon?

Back

Transportation is the greatest contributor to atmospheric carbon due to emissions from vehicles.

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 are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, containing high levels of carbon, and are used as energy sources.

Front

What is the significance of glucose (C6H12O6) in the Carbon Cycle?

Back

Glucose is a primary energy source for living organisms and is produced during photosynthesis; it contains carbon that is cycled through the ecosystem.

Front

How does combustion affect the Carbon Cycle?

Back

Combustion of fossil fuels releases carbon dioxide into the atmosphere, increasing greenhouse gas concentrations and impacting climate change.
