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 such as photosynthesis, respiration, decomposition, and combustion.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals that have been buried underground for millions of years. Examples include coal, oil, and natural gas.

Front

How do plants contribute to the Carbon Cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into glucose and oxygen, thus playing a crucial role in reducing atmospheric CO2 levels.

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 and water as byproducts.

Front

What happens to carbon in dead organisms?

Back

When organisms die, their bodies can decompose, releasing carbon back into the soil and atmosphere, or they can be buried and transformed into fossil fuels over millions of years.

Front

What role do decomposers play in the Carbon Cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, which is essential for nutrient cycling.

Front

What is combustion?

Back

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

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, contributing to global warming and climate change.

Front

What are the main sources of carbon dioxide emissions?

Back

The main sources of carbon dioxide emissions include burning fossil fuels for energy, deforestation, and industrial processes.
