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.

What do plants depend on for photosynthesis?

Back

Plants depend on carbon dioxide for photosynthesis.

Front

What do humans depend on for respiration?

Back

Humans depend on oxygen for respiration.

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?

Back

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

Front

What is combustion?

Back

Combustion is a chemical process in which a substance reacts with oxygen to produce heat and light, commonly referred to as burning.

Front

How does photosynthesis affect carbon levels in the atmosphere?

Back

Photosynthesis removes carbon dioxide from the atmosphere and releases oxygen.

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 is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does combustion contribute to the carbon cycle?

Back

Combustion releases carbon dioxide into the atmosphere, contributing to the carbon cycle.
