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 is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide and sunlight into glucose and oxygen.

Front

What role do plants play in the carbon cycle?

Back

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

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen to produce heat and light, often resulting in the release of carbon dioxide.

Front

What are fossil fuels?

Back

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

Front

How do animals contribute to the carbon cycle?

Back

Animals contribute to the carbon cycle through respiration, where they inhale oxygen and exhale carbon dioxide.

Front

What is respiration?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What happens to carbon during decomposition?

Back

During decomposition, microorganisms break down dead organic matter, releasing carbon back into the atmosphere as carbon dioxide.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for maintaining the balance of carbon in the environment, supporting life, and regulating Earth's climate.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases, including carbon dioxide, in the atmosphere.
