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

Front

What gas do plants take in during photosynthesis?

Back

Carbon dioxide (CO2)

Front

What do plants release as a byproduct of photosynthesis?

Back

Oxygen (O2)

Front

How do animals contribute to the carbon cycle?

Back

Animals breathe in oxygen and exhale carbon dioxide, which is used by plants for photosynthesis.

Front

What is the role of decomposers in the carbon cycle?

Back

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

Front

What human activity significantly increases carbon dioxide levels in the atmosphere?

Back

The burning of fossil fuels.

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 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 as a byproduct.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily consisting of carbon, and are used as energy sources.

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 proteins, lipids, carbohydrates, and nucleic acids.
