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 various processes such as photosynthesis, respiration, decomposition, and combustion.

Front

What role do oceans play in the carbon cycle?

Back

Oceans absorb carbon dioxide from the atmosphere and are home to marine organisms that use carbonic acid to form shells, thus playing a crucial role in the carbon cycle.

Front

Why is carbon essential for life?

Back

Carbon is the central element in all living organisms, forming the backbone of organic molecules such as proteins, lipids, carbohydrates, and nucleic acids.

Front

How do humans contribute to the increase of carbon in the atmosphere?

Back

Humans increase atmospheric carbon by burning fossil fuels (coal, oil), deforestation, and industrial processes, which release carbon dioxide into the atmosphere.

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, using chlorophyll.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which animals and plants take in oxygen and release carbon dioxide as they convert glucose into energy.

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that helps trap heat in the atmosphere, keeping the Earth warm enough to support life.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen, releasing energy in the form of heat and light, and producing carbon dioxide and water.

Front

What is decay in the carbon cycle?

Back

Decay is the process by which dead organic matter is broken down by decomposers, returning carbon to the soil and atmosphere.

Front

What are fossil fuels?

Back

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