Carbon Cycle

What is the carbon cycle?

• The carbon cycle is the process of converting sunlight into energy for plants

• The carbon cycle is the process of converting carbon dioxide into oxygen

• The carbon cycle is the process of exchanging nitrogen between the atmosphere and living organisms

• The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, ocean, and living organisms.

Explain the process of photosynthesis and its role in the carbon cycle.

• Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. During this process, carbon dioxide is taken in from the atmosphere and oxygen is released.

• Photosynthesis only occurs in animals, not plants

• Photosynthesis has no role in the carbon cycle

• Photosynthesis is the process of converting oxygen into carbon dioxide

Describe the role of producers in the carbon cycle.

• Producers release carbon dioxide during photosynthesis

• Producers have no role in the carbon cycle

• Producers absorb carbon dioxide during photosynthesis and release oxygen.

• Producers only absorb oxygen and release carbon dioxide

What are the main reservoirs of carbon in the carbon cycle?

• Atmosphere, hydrosphere, lithosphere, cryosphere

• Atmosphere, oceans, biosphere, lithosphere

• Biosphere, stratosphere, lithosphere, troposphere

• Atmosphere, biosphere, mesosphere, lithosphere

Explain the process of respiration and its role in the carbon cycle.

• Respiration has no role in the carbon cycle

• Respiration is the process of converting carbon dioxide into oxygen

• Respiration only occurs in plants and not in animals

• Respiration is the process by which organisms exchange gases with their environment, taking in oxygen and releasing carbon dioxide. In the carbon cycle, respiration releases carbon dioxide into the atmosphere, which is then used by plants during photosynthesis to produce oxygen and organic compounds.

How do human activities impact the carbon cycle?

• Human activities have no impact on the carbon cycle

• Using renewable energy sources reduces carbon emissions

• Burning fossil fuels and deforestation release excess carbon dioxide into the atmosphere.

• Eating meat has no effect on carbon levels

Discuss the role of decomposers in the carbon cycle.

• They have no impact on the carbon cycle.

• They convert carbon dioxide into oxygen through photosynthesis.

• They absorb carbon dioxide from the atmosphere and store it in the soil.

• They break down dead organisms and organic matter, releasing carbon dioxide back into the atmosphere.

What is the significance of the carbon cycle in maintaining the balance of gases in the atmosphere?

• It causes an increase in greenhouse gases in the atmosphere

• It has no impact on the atmosphere

• It regulates the amount of carbon dioxide in the atmosphere

• It only affects the levels of oxygen in the atmosphere

Explain the process of combustion and its impact on the carbon cycle.

• Combustion releases carbon dioxide into the atmosphere, impacting the carbon cycle by increasing the amount of carbon dioxide in the atmosphere.

• Combustion releases oxygen into the atmosphere, decreasing the amount of carbon dioxide in the atmosphere.

• Combustion has no impact on the carbon cycle.

• Combustion absorbs carbon dioxide from the atmosphere, decreasing the amount of carbon dioxide in the atmosphere.

How does deforestation affect the carbon cycle?

• It only affects the carbon levels in the soil

• It decreases atmospheric carbon levels

• It increases atmospheric carbon levels

• It has no impact on atmospheric carbon levels
