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, converting it into organic matter and releasing oxygen.

Front

How do oceans contribute to the carbon cycle?

Back

Oceans absorb carbon dioxide from the atmosphere, which is used by marine plants and algae for photosynthesis, and also contributes to the formation of carbonate minerals.

Front

What happens to carbon when organisms die in the ocean?

Back

When organisms die in the ocean, they may sink to the bottom and over time, their remains can form limestone rock.

Front

What is the effect of burning fossil fuels on the carbon cycle?

Back

Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere, contributing to climate change.

Front

How does carbon dioxide enter the ocean?

Back

Carbon dioxide from the atmosphere is absorbed directly into the surface ocean.

Front

What happens to atmospheric carbon levels if plant populations decrease?

Back

If plant populations decrease, the amount of carbon in the atmosphere would increase due to reduced absorption by plants.

Front

What do ocean coral and oysters use carbon for?

Back

Ocean coral and oysters use carbon to create shells, which are made of calcium carbonate.

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.

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, releasing carbon dioxide as a byproduct.
