What is the Carbon Cycle?

Back

The Carbon Cycle is the process by which carbon is exchanged between the Earth's atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, decomposition, and combustion.

What is Combustion?

Back

Combustion is a chemical process in which a substance (usually a fossil fuel) reacts with oxygen to produce energy, carbon dioxide, and water.

What is a Carbon Sink?

Back

A Carbon Sink is a natural or artificial reservoir that absorbs and stores carbon from the atmosphere, such as forests, oceans, and soil.

What is Decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, releasing carbon back into the soil and atmosphere.

How does respiration contribute to the Carbon Cycle?

Back

Respiration by animals and plants releases carbon dioxide back into the atmosphere, contributing to the Carbon Cycle.

What is the significance of the Atmosphere in the Carbon Cycle?

Back

The Atmosphere is a key component of the Carbon Cycle, as it is where carbon dioxide is stored and exchanged with living organisms and the environment.
