Carbon Cycle Practice

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 such as photosynthesis, respiration, decomposition, and combustion.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using sunlight.

Front

What is respiration in the context of 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.

Front

What role do fossil fuels play in the carbon cycle?

Back

Fossil fuels are natural resources formed from the remains of dead plants and animals. When burned, they release carbon dioxide into the atmosphere, contributing to the carbon cycle.

Front

What is decomposition?

Back

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

Front

What is combustion?

Back

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

Front

How does carbon dioxide enter the atmosphere?

Back

Carbon dioxide enters the atmosphere through processes like respiration, combustion of fossil fuels, and volcanic eruptions.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for regulating Earth's climate, supporting life, and maintaining the balance of carbon in the environment.

Front

What is the role of plants in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter and releasing oxygen.

Front

What is the impact of human activities on the carbon cycle?

Back

Human activities, such as burning fossil fuels and deforestation, increase carbon dioxide levels in the atmosphere, contributing to climate change.
