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.

What do organisms that do not decompose become when buried?

Back

Fossil fuels.

Front

What is the main reason for the increase in Earth's average temperature over the past century?

Back

Higher levels of carbon dioxide and other greenhouse gases in the atmosphere.

Front

What do plants produce during photosynthesis using carbon dioxide?

Back

Food.

Front

What is the correct equation for photosynthesis?

Back

CO₂ + light + H₂O → O₂ + glucose.

Front

What happens to carbon during the carbon cycle?

Back

Carbon changes forms but is never lost; it is recycled through various processes.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which organisms convert glucose and oxygen into energy, carbon dioxide, and water.

Front

How do fossil fuels relate to the carbon cycle?

Back

Fossil fuels are formed from the remains of ancient organisms that were buried and subjected to heat and pressure over millions of years.

Front

What is the significance of decomposers in the carbon cycle?

Back

Decomposers break down dead organisms, returning carbon to the soil and atmosphere.
