The Carbon Cycle

What is the carbon cycle?

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

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

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

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

Explain the process of carbon fixation in the carbon cycle.

• During carbon fixation, plants use moonlight to convert carbon dioxide into glucose

• During carbon fixation, animals use sunlight to convert oxygen into glucose

• During carbon fixation, plants use sunlight to convert carbon dioxide into glucose, which is then used for energy and growth.

• During carbon fixation, plants use water to convert carbon dioxide into glucose

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

• atmosphere, hydrosphere, lithosphere, cryosphere

• atmosphere, biosphere, asthenosphere, lithosphere

• atmosphere, oceans, biosphere, lithosphere

• biosphere, stratosphere, lithosphere, troposphere

How does carbon move between the different reservoirs in the carbon cycle?

• Through processes such as knitting, sewing, and crocheting.

• Through processes such as boiling, freezing, and melting.

• By using a teleportation device.

• Through processes such as photosynthesis, respiration, decomposition, and combustion.

What role do plants play in the carbon cycle?

• Absorb carbon dioxide and release oxygen

• Release carbon dioxide and absorb oxygen

• Have no impact on the carbon cycle

• Consume oxygen and release carbon monoxide

Describe the process of respiration in the context of the carbon cycle.

• Organisms release energy from organic compounds and produce carbon dioxide as a byproduct.

• During respiration, organisms absorb carbon dioxide and release oxygen.

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

• Organisms release energy from inorganic compounds and produce oxygen as a byproduct.

How does deforestation impact the carbon cycle?

• Deforestation reduces the amount of oxygen in the atmosphere.

• Deforestation reduces the number of trees that can absorb carbon dioxide from the atmosphere.

• Deforestation has no impact on the carbon cycle.

• Deforestation increases the number of trees that can absorb carbon dioxide from the atmosphere.

Explain the concept of carbon sequestration and its significance in the carbon cycle.

• Carbon sequestration is the process of releasing carbon dioxide into the atmosphere

• Carbon sequestration has no significance in the carbon cycle

• Carbon sequestration is the process of capturing and storing carbon dioxide to prevent it from entering the atmosphere. It is significant in the carbon cycle as it helps to reduce the amount of carbon dioxide in the atmosphere, mitigating climate change.

• Carbon sequestration only occurs in the oceans

What are the human activities that contribute to the disruption of the carbon cycle?

• Planting more trees

• Reducing carbon emissions

• Using renewable energy

• Burning fossil fuels, deforestation, and industrial processes

Discuss the potential consequences of an imbalance in the carbon cycle.

• Increased levels of carbon dioxide in the atmosphere, global warming, climate change, disrupted ecosystems, and ocean acidity imbalance

• Balanced ecosystems and stable climate conditions

• Decreased levels of carbon dioxide in the atmosphere, leading to a lack of plant growth

• Increased levels of oxygen in the atmosphere, causing respiratory problems for humans and animals
