What process removes carbon dioxide from the atmosphere?

Back

Photosynthesis is the process by which plants convert carbon dioxide into oxygen and glucose using sunlight.

Front

When humans burn fossil fuels, where does most of the carbon go?

Back

Most of the carbon enters the atmosphere as carbon dioxide.

Front

What is considered the 'long term' part of the carbon cycle?

Back

Fossilized remains becoming coal, oil, and natural gas is considered the long-term part of the carbon cycle.

Front

How do living organisms return carbon to the atmosphere?

Back

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

Front

What is a true statement about humans and plants?

Back

Humans depend on oxygen, while plants depend on carbon dioxide.

Front

What is the role of photosynthesis in the carbon cycle?

Back

Photosynthesis removes carbon dioxide from the atmosphere and converts it into organic matter.

Front

What happens during respiration in the carbon cycle?

Back

During respiration, 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 available to absorb carbon dioxide, increasing atmospheric carbon levels.

Front

How do fossil fuels relate to the carbon cycle?

Back

Fossil fuels store carbon that was once part of living organisms, and burning them releases carbon dioxide back into the atmosphere.

Front

What is decomposition in the context of the carbon cycle?

Back

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