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 combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen to produce heat and light, commonly referred to as burning.

Front

What is a carbon sink?

Back

A carbon sink is a natural or artificial reservoir that absorbs more carbon than it releases, helping to reduce the amount of carbon dioxide in the atmosphere.

Front

What is the role of plants in 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 carbon.

Front

What happens to carbon dioxide levels if plant populations decrease?

Back

If plant populations decrease, the amount of carbon dioxide in the atmosphere would increase due to reduced absorption by plants.

Front

What are the end products of cellular respiration?

Back

The end products of cellular respiration are carbon dioxide, water, and ATP energy.

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 is the significance of oceans in the carbon cycle?

Back

Oceans act as a major carbon sink, absorbing large amounts of carbon dioxide from the atmosphere and helping to regulate global climate.

Front

What is the impact of fossil fuel combustion on the carbon cycle?

Back

The combustion of fossil fuels releases significant amounts of carbon dioxide into the atmosphere, contributing to climate change and disrupting the natural carbon cycle.
