What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, decomposition, and combustion.

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are oxygen and glucose.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

How do animals contribute to the carbon cycle?

Back

Animals contribute to the carbon cycle through respiration, where they inhale oxygen and exhale carbon dioxide.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, which is essential for nutrient cycling.

Front

What is combustion?

Back

Combustion is the process of burning fossil fuels or biomass, which releases carbon dioxide into the atmosphere.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, including coal, oil, and natural gas, that store carbon.

Front

What is the greatest contributor to atmospheric carbon?

Back

Transportation is one of the greatest contributors to atmospheric carbon due to the burning of fossil fuels.

Front

What happens to carbon during the carbon cycle?

Back

Carbon changes forms during the carbon cycle, moving between the atmosphere, living organisms, and the earth, but the total amount of carbon remains constant.
