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 like photosynthesis, respiration, decomposition, and combustion.

How do living organisms return carbon to the atmosphere?

Back

Living organisms return carbon to the atmosphere primarily through respiration and decomposition.

Front

What is CO2?

Back

CO2 stands for Carbon Dioxide, a colorless gas that is a byproduct of respiration and combustion, and is used by plants during photosynthesis.

Front

What role do plants play in the Carbon Cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen, thus playing a crucial role in the carbon cycle.

Front

What is respiration in the context of the Carbon Cycle?

Back

Respiration is the process by which living organisms take in oxygen and release carbon dioxide as a waste product.

Front

What is decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, returning carbon to the atmosphere and soil.

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

Why is carbon important for life?

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 impact of human activities on the Carbon Cycle?

Back

Human activities, such as burning fossil fuels and deforestation, increase carbon dioxide levels in the atmosphere, contributing to climate change.

Front

What is the difference between carbon monoxide and carbon dioxide?

Back

Carbon monoxide (CO) is a toxic gas produced by incomplete combustion, while carbon dioxide (CO2) is a non-toxic gas essential for photosynthesis.
