Carbon Cycle

Front

What is the Carbon Cycle?

Back

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

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 carbon dioxide and water, producing oxygen as a byproduct.

Front

What role do decomposers play in the Carbon Cycle?

Back

Decomposers break down dead plants and animals, returning carbon to the soil and atmosphere, and making nutrients available for new plant growth.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily composed of carbon, and are used as energy sources.

Front

How does burning fossil fuels affect the Carbon Cycle?

Back

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

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, producing carbon dioxide and water as byproducts.

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, playing a crucial role in regulating Earth's temperature.

Front

How do plants contribute to the Carbon Cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, using it to grow and release oxygen back into the atmosphere.

Front

What happens to carbon in dead organisms?

Back

When organisms die, their carbon is released back into the environment through decomposition or can be buried and transformed into fossil fuels over millions of years.

Front

What is the role of the ocean in the Carbon Cycle?

Back

The ocean absorbs a significant amount of carbon dioxide from the atmosphere, helping to regulate global carbon levels and supporting marine life.
