What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms. It involves various processes such as photosynthesis, respiration, decomposition, and combustion.

What happens to carbon when fossil fuels are burned?

Back

When fossil fuels are burned, carbon is released into the atmosphere as carbon dioxide.

Front

How do living organisms return carbon to the atmosphere?

Back

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

Front

What is the current trend of carbon levels in the atmosphere?

Back

The amount of carbon in the atmosphere is increasing.

Front

How is carbon transferred in food chains?

Back

Carbon in plants moves to animals that eat them, and when one animal eats another, the carbon is transferred.

Front

What is a key fact about the total amount of carbon on Earth?

Back

There is as much carbon on Earth as when it was formed; it is recycled but not created or lost.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert organic matter back into carbon dioxide, releasing it into the atmosphere.

Front

What is decomposition?

Back

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

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that contributes to global warming and climate change.
