Carbon Cycle Review

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

What process releases carbon dioxide into the atmosphere?

Back

Burning fossil fuels, cellular respiration, and decomposing organic matter all release carbon dioxide into the atmosphere.

Front

Which process removes carbon dioxide from the atmosphere?

Back

Photosynthesis removes carbon dioxide from the atmosphere by converting it into glucose using sunlight.

Front

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

How do animals obtain carbon?

Back

Animals obtain carbon by eating plants and other animals, which contain carbon in their organic compounds.

Front

What is respiration in terms of the carbon cycle?

Back

Respiration is the process by which animals and plants take in oxygen and release carbon dioxide as a byproduct of breaking down glucose for energy.

Front

What does NOT produce carbon dioxide?

Back

Photosynthesis does not produce carbon dioxide; instead, it consumes it.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, releasing carbon back into the atmosphere as carbon dioxide.

Front

What is the significance of carbon in living organisms?

Back

Carbon is a fundamental building block of life, forming the backbone of organic molecules such as carbohydrates, proteins, lipids, and nucleic acids.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen, releasing energy in the form of heat and light, and producing carbon dioxide and water.
