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 various processes such as photosynthesis, respiration, decomposition, and combustion.

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight, water, and carbon dioxide to create their own food (glucose) and release oxygen as a byproduct.

What is respiration in the carbon cycle?

Back

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

What is decomposition?

Back

Decomposition is the process by which dead plants and animals are broken down by microorganisms, releasing carbon back into the soil and atmosphere as carbon dioxide.

What is combustion?

Back

Combustion is the process of burning organic materials, such as fossil fuels and biomass, which releases carbon dioxide into the atmosphere.

How does carbon dioxide enter the atmosphere?

Back

Carbon dioxide enters the atmosphere through respiration, decomposition, combustion, and volcanic eruptions.

Front

How do plants contribute to the carbon cycle?

Back

Plants contribute to the carbon cycle by absorbing carbon dioxide during photosynthesis and releasing oxygen.

What role do animals play in the carbon cycle?

Back

Animals play a role in the carbon cycle by consuming plants and other animals, and releasing carbon dioxide through respiration.

What is the significance of the carbon cycle?

Back

The carbon cycle is significant because it regulates the Earth's climate, supports life by providing essential nutrients, and helps maintain the balance of carbon in the environment.

What happens to carbon during decomposition?

Back

During decomposition, carbon from dead organisms is released back into the soil and atmosphere as carbon dioxide, enriching the soil and contributing to the carbon cycle.
