The 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

TRUE or FALSE: All of the carbon on Earth is continually recycled in the carbon cycle.

Back

True

Front

What gas do producers take in during the carbon cycle?

Back

Carbon dioxide (CO2)

Front

When humans burn fossil fuels, where does most of the carbon enter as carbon dioxide?

Back

The atmosphere

Front

TRUE or FALSE: Carbon atoms cannot be created or destroyed.

Back

True

Front

What is the molecular formula for carbon dioxide?

Back

CO2

Front

What role do plants play in the carbon cycle?

Back

Plants act as producers by taking in carbon dioxide during photosynthesis and converting it into glucose and oxygen.

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 chlorophyll, converting 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 decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus playing a crucial role in recycling carbon.
