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.

Front

TRUE or FALSE? All of the carbon in existence is continually recycled in the carbon cycle.

Back

True

Front

Why is burning fossil fuels harmful?

Back

It increases the amount of carbon dioxide in the atmosphere.

Front

How is the carbon cycle similar to the water cycle?

Back

Both involve the transfer of substances between animals, plants, and the Earth.

Front

Which gas do animals release that plants depend on for survival?

Back

Carbon dioxide.

Front

What is a greenhouse gas?

Back

A greenhouse gas is a gas that traps heat in the atmosphere, contributing to the greenhouse effect. Examples include carbon dioxide, methane, and nitrous oxide.

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 regulating carbon levels.

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 back into the atmosphere.

Front

What is the impact of deforestation on the carbon cycle?

Back

Deforestation reduces the number of trees that can absorb carbon dioxide, leading to increased levels of carbon dioxide in the atmosphere.
