What is the primary function of photosynthesis in the carbon cycle?

• To convert oxygen into carbon dioxide and release organic compounds

• To convert carbon dioxide into organic compounds and release oxygen

• To convert organic compounds into carbon dioxide and release water

• To convert water into carbon dioxide and release oxygen

How do greenhouse gases contribute to the greenhouse effect?

• They cool down the Earth's atmosphere

• They reflect 90% of solar radiation out of the Earth's atmosphere

• They trap heat in the Earth's atmosphere

• They have no impact on the greenhouse effect

Select three common greenhouse gases and explain their sources.

• Carbon dioxide (CO2) from burning fossil fuels and deforestation

• Oxygen (O2) from burning fossil fuels

• Methane (CH4) from agriculture and natural gas production

• Nitrous oxide (N2O) from agricultural and industrial activities

How does deforestation impact the carbon cycle and greenhouse effect?

• Deforestation reduces the number of trees that can absorb carbon dioxide, increasing the greenhouse effect.

• Deforestation reduces the amount of greenhouse gases in the atmosphere.

• Deforestation increases the number of trees that can absorb carbon dioxide, reducing the greenhouse effect.

• Deforestation has no impact on the carbon cycle or greenhouse effect

Explain the process of carbon fixation in the carbon cycle.

• Plants convert carbon dioxide into nitrogen gas through photosynthesis.

• Plants convert carbon dioxide into organic compounds through photosynthesis.

• Carbon fixation involves the release of carbon dioxide into the atmosphere.

• Carbon fixation is the process of converting organic compounds into carbon dioxide.

Describe the role of decomposition in the carbon cycle.

• It helps in breaking down organic matter and releasing carbon dioxide back into the atmosphere.

• It helps in absorbing carbon dioxide from the atmosphere

• It only occurs in aquatic ecosystems

• It has no role in the carbon cycle

Where does the carbon in the carbon cycle come from?

• Volcanic eruptions create new carbon by adding it to the atmosphere and lithosphere.

• Carbon is recycled into different compounds through the many processes and steps of the carbon cycle.

• Erosion and photosynthesis manufacture new carbon atoms, which enter the carbon cycle at different places.

• Carbon is only created by, and moves back and forth to the biosphere through photosynthesis and decomposition.
