Carbon Cycle Review

What are the stages of the carbon cycle?

• Carbon absorption, Carbon emission, Carbon accumulation, Carbon retention

• Carbon production, Carbon elimination, Carbon preservation, Carbon conservation

• Carbon assimilation, Carbon excretion, Carbon retention, Carbon storage

• Carbon fixation, Carbon release, Carbon storage, Carbon sequestration

How does the carbon cycle affect the Earth?

• It regulates the amount of carbon dioxide in the atmosphere and affects the Earth's climate and temperature.

• It has no impact on the Earth's climate and temperature.

• It only affects the carbon levels in the oceans, not the atmosphere.

• It increases the amount of carbon dioxide in the atmosphere, leading to global cooling.

What are the effects of the carbon cycle on biodiversity?

• Biodiversity is not influenced by changes in the carbon cycle.

• The carbon cycle only affects plants, not animals.

• Changes in the carbon cycle can impact the distribution and abundance of species, as well as their ability to adapt to environmental changes.

• The carbon cycle has no effect on biodiversity.

What happens to the carbon stored in fossil fuels when they are burned?

• The carbon is converted into oxygen gas.

• The carbon is converted into water vapor.

• The carbon stored in fossil fuels is released into the atmosphere as carbon dioxide gas.

• The carbon is absorbed by the ground.

How does the carbon cycle regulate the Earth's climate?

• By balancing the levels of carbon dioxide in the atmosphere

• By trapping heat in the atmosphere

• By decreasing the levels of carbon dioxide in the atmosphere

• By increasing the levels of carbon dioxide in the atmosphere

What are some natural sources of carbon dioxide in the atmosphere?

• Burning fossil fuels, deforestation, and industrial processes.

• Human respiration, combustion of biomass, and weathering of rocks.

• Volcanic eruptions, respiration by plants and animals, and the decay of organic matter.

• Photosynthesis, oceanic absorption, and soil respiration.

How does deforestation contribute to the carbon cycle imbalance?

• Reduces the number of trees available to absorb carbon dioxide

• Causes the release of oxygen into the atmosphere

• Has no effect on the carbon cycle

• Increases the number of trees available to absorb carbon dioxide
