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 various processes such as photosynthesis, respiration, decomposition, and combustion.

Front

What process do plants use to absorb carbon dioxide from the atmosphere?

Back

Photosynthesis.

Front

What happens to carbon levels in the atmosphere if plant populations decrease?

Back

The amount of carbon in the atmosphere would increase.

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 role do decomposers play in the carbon cycle?

Back

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

Front

What is limestone primarily made from?

Back

Limestone is primarily made from the shells of dead sea organisms.

Front

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

Back

True.

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that helps regulate Earth's temperature and is essential for photosynthesis.

Front

What is fossilization?

Back

Fossilization is the process by which organic material is preserved in sedimentary rock, often involving the replacement of organic material with minerals.

Front

How does combustion affect the carbon cycle?

Back

Combustion releases carbon dioxide into the atmosphere, contributing to the greenhouse effect and climate change.
