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 such as photosynthesis, respiration, decomposition, and combustion.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting 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, producing carbon dioxide and water as byproducts.

Front

What role do decomposers play in the carbon cycle?

Back

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

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light, and releasing carbon dioxide and other gases into the atmosphere.

Front

Why is oxygen important in the carbon cycle?

Back

Oxygen is essential for respiration in animals and plants, and it is produced during photosynthesis, linking the two processes in the carbon cycle.

Front

What is the significance of carbon in living organisms?

Back

Carbon is a fundamental building block of life, forming the backbone of organic molecules such as proteins, lipids, carbohydrates, and nucleic acids.

Front

How does human activity impact the carbon cycle?

Back

Human activities, such as burning fossil fuels and deforestation, increase carbon dioxide levels in the atmosphere, disrupting the natural carbon cycle and contributing to climate change.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases, including carbon dioxide, which are released through natural processes and human activities.

Front

What is carbon sequestration?

Back

Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide to mitigate climate change, often through natural processes like reforestation or technological methods.
