What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is continuously transferred between organisms and the physical environment.

Front

What are the main reservoirs of carbon in the environment?

Back

Carbon is stored in the atmosphere, oceans, soil, and living organisms.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis and convert it into glucose.

Front

How do animals contribute to the carbon cycle?

Back

Animals release carbon dioxide into the atmosphere through cellular respiration.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organisms, releasing carbon back into the soil and atmosphere.

Front

How does carbon move from the atmosphere to the oceans?

Back

Carbon dioxide dissolves in ocean water, forming carbonic acid and other compounds.

Front

What is the role of fossil fuels in the carbon cycle?

Back

Burning fossil fuels releases stored carbon into the atmosphere as carbon dioxide.

Front

How does the carbon cycle affect energy transfer in ecosystems?

Back

Carbon compounds like glucose store energy, which is transferred through food chains.

Front

What human activities impact the carbon cycle?

Back

Activities like deforestation and burning fossil fuels disrupt the natural balance of the carbon cycle.

Front

Why is the carbon cycle important for life on Earth?

Back

It ensures the availability of carbon for essential processes like photosynthesis and cellular respiration.
