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 happens when humans burn fossil fuels?

Back

When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.

Front

What is combustion?

Back

Combustion is a chemical process in which a substance reacts with oxygen to produce heat and light, often resulting in the release of carbon dioxide.

Front

What is decomposition?

Back

Decomposition is the process by which organic matter is broken down by bacteria and fungi, returning nutrients to the soil and releasing carbon.

Front

True or False: Animals decomposing into the ground increases the amount of carbon in the soil.

Back

True.

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

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, using it to produce oxygen and glucose.

Front

What is the role of bacteria in the carbon cycle?

Back

Bacteria play a crucial role in decomposition, breaking down organic matter and releasing carbon back into the soil and atmosphere.

Front

What impact does deforestation have on the carbon cycle?

Back

Deforestation reduces the number of trees that can absorb carbon dioxide, leading to increased levels of carbon in the atmosphere.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert oxygen and glucose into energy, releasing carbon dioxide as a byproduct.
