Carbon Cycle

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon atoms move through the Earth's atmosphere, land, and oceans, involving processes like photosynthesis, respiration, and decomposition.

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 is the main source of carbon for plants?

Back

The main source of carbon for plants is the carbon dioxide molecules they absorb from the atmosphere.

Front

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis, converting it into organic matter, which is then passed through the food chain.

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 back into the atmosphere.

Front

What role do decomposers play in the carbon cycle?

Back

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

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, and fats.

Front

What is the difference between carbon sinks and carbon sources?

Back

Carbon sinks are natural systems that absorb more carbon than they release (e.g., forests), while carbon sources release more carbon than they absorb (e.g., fossil fuel combustion).

Front

How does the carbon cycle affect climate change?

Back

The carbon cycle affects climate change by regulating the levels of carbon dioxide in the atmosphere; increased carbon emissions from human activities enhance the greenhouse effect.
