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.

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 is decomposition?

Back

Decomposition is the process by which organic substances are broken down into simpler organic or inorganic matter, often involving the action of microorganisms.

What role do fossil fuels play in the carbon cycle?

Back

Fossil fuels, such as coal, oil, and natural gas, store carbon that was captured by ancient plants and animals. When burned for energy, they release carbon dioxide back into the atmosphere.

Front

What is combustion?

Back

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

Front

How does predation affect the carbon cycle?

Back

Predation affects the carbon cycle by transferring carbon from prey to predators, as predators consume prey and incorporate the carbon into their own bodies.

Front

What is the significance of nitrogen fixation in ecosystems?

Back

Nitrogen fixation is the process by which nitrogen in the atmosphere is converted into ammonia or related compounds in soil, which is essential for plant growth and indirectly supports the carbon cycle.

Front

What is the impact of burning fossil fuels on the carbon cycle?

Back

Burning fossil fuels increases the amount of carbon dioxide in the atmosphere, contributing to climate change and disrupting the natural balance of the carbon cycle.

Front

What is the role of plants in the carbon cycle?

Back

Plants play a crucial role in the carbon cycle by absorbing carbon dioxide during photosynthesis and releasing oxygen, thus helping to regulate atmospheric carbon levels.
