Carbon Cycle

Front

What is the carbon cycle?

Back

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

How does carbon get into the soil?

Back

Carbon gets into the soil when a human dies, when a plant dies, and when an animal dies.

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What happens to the amount of carbon during cellular respiration?

Back

The amount of carbon stays the same.

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 combustion?

Back

Combustion is a chemical reaction that occurs when a substance (usually a fossil fuel) reacts with oxygen to produce heat, light, carbon dioxide, and water.

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

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 role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce atmospheric carbon levels.

Front

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

Back

Burning fossil fuels releases carbon dioxide into the atmosphere, increasing greenhouse gas concentrations and contributing to climate change.
