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 decomposers play in the carbon cycle?

Back

Decomposers, such as mushrooms, break down dead organic matter, returning carbon to the soil and atmosphere, which is essential for nutrient cycling.

Front

What gas do plants take in during photosynthesis?

Back

Plants take in carbon dioxide (CO2) during photosynthesis.

Front

What do plants release during photosynthesis that is vital for animal life?

Back

Plants release oxygen (O2) during photosynthesis, which is essential for animals to breathe.

Front

How do animals contribute to the carbon cycle?

Back

Animals contribute to the carbon cycle by breathing in oxygen and releasing carbon dioxide through respiration.

Front

What happens to oxygen levels in the environment during a forest fire?

Back

Oxygen levels decrease in the environment during a forest fire due to combustion.

Front

True or False: All of the carbon in existence is continually recycled in the carbon cycle.

Back

True.

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 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 is the significance of the carbon cycle for life on Earth?

Back

The carbon cycle is crucial for maintaining the balance of carbon in the environment, supporting life by providing essential nutrients and regulating climate.
