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.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and convert it into glucose, releasing oxygen as a byproduct.

Front

What is a carbon sink?

Back

A carbon sink is a natural or artificial reservoir that stores carbon-containing chemical compounds for an indefinite period. Examples include forests, oceans, and soil.

Front

What happens to carbon in dead organisms?

Back

When organisms die, their carbon is released back into the soil through the process of decomposition, where it can be used by plants or converted into fossil fuels over time.

Front

What is decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, returning nutrients, including carbon, to the soil.

Front

How do animals contribute to the carbon cycle?

Back

Animals consume plants and other animals, releasing carbon dioxide back into the atmosphere through respiration.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the significance of oxygen in the carbon cycle?

Back

Oxygen is produced by plants during photosynthesis and is essential for the respiration of animals, creating a balance in the ecosystem.

Front

What is carbon dioxide?

Back

Carbon dioxide is a colorless, odorless gas that is a key component of the carbon cycle, produced by respiration and combustion, and absorbed by plants during photosynthesis.

Front

What is the impact of forest fires on the carbon cycle?

Back

Forest fires release large amounts of carbon dioxide into the atmosphere, reducing the amount of carbon stored in trees and affecting the overall carbon balance.
