13 - The Carbon Cycle - PowerPoint

Open Ended

In what ways do living and non-living components interact in the carbon cycle?

Multiple Choice

Why is the carbon cycle considered important for life on Earth?

• Because it helps regulate the Earth's temperature and supports life processes

• Because it only affects plants

• Because it is responsible for the water cycle

• Because it only involves non-living things

Multiple Choice

• Fats

• Vitamins

• Minerals

• Water

Open Ended

Why are all living things on Earth referred to as carbon-based life forms?

Fill in the Blank

Open Ended

Explain the difference between biotic and abiotic carbon reservoirs using examples from the carbon cycle.

Multiple Select

Which of the following are examples of abiotic carbon reservoirs?

• CO2 in the atmosphere

• Producers

• Consumers

• Calcium carbonate in rocks

Open Ended

How does carbon dioxide in the atmosphere cause the greenhouse effect?

Open Ended

How does an increase in greenhouse gases like CO2 lead to climate change according to the carbon cycle?

Multiple Choice

Which of the following best describes the greenhouse effect as shown in the diagram?

• Solar radiation is completely absorbed by the Earth's surface.

• All heat escapes into space after reaching Earth.

• Some heat is trapped by greenhouse gases like CO2, warming the atmosphere.

• CO2 directly absorbs all solar radiation.

Multiple Select

Which of the following are considered decomposers in the carbon cycle?
