Carbon Cycle

What is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen?

• Transpiration

• Fermentation

• Respiration

• Photosynthesis

What is the process by which animals and plants release energy from glucose and produce carbon dioxide and water as byproducts?

• Cellular respiration

• Photosynthesis

• Oxidative phosphorylation

• Fermentation

What is the process by which dead plants and animals are broken down by bacteria and fungi, releasing carbon dioxide back into the atmosphere?

• Decomposition

• Fossilization

• Photosynthesis

• Combustion

What is the process by which carbon that has been stored underground for millions of years is released into the atmosphere when fossil fuels are burned?

• Combustion

• Sublimation

• Condensation

• Evaporation

What is the process by which trees are cut down, releasing the carbon they have stored into the atmosphere?

• Reforestation

• Carbon sequestration

• Deforestation

• Tree preservation

What is the chemical element that is the basis of all living organisms and is found in various forms in the atmosphere, oceans, and Earth's crust?

• Carbon

• Nitrogen

• Hydrogen

• Oxygen

What is the gas that is produced by various natural and human activities and is a major contributor to the greenhouse effect and global warming?

• nitrous oxide (N2O)

• methane (CH4)

• carbon dioxide (CO2)

• oxygen (O2)

How does photosynthesis contribute to the carbon cycle?

• Photosynthesis contributes to the carbon cycle by converting organic compounds into carbon dioxide

• Photosynthesis contributes to the carbon cycle by removing carbon dioxide from the atmosphere and converting it into organic compounds.

• Photosynthesis contributes to the carbon cycle by increasing the amount of carbon dioxide in the atmosphere

• Photosynthesis contributes to the carbon cycle by releasing carbon dioxide into the atmosphere

How does deforestation impact the carbon cycle?

• Deforestation leads to the absorption of excess carbon dioxide by the soil, balancing the carbon cycle.

• Deforestation has no impact on the carbon cycle.

• Deforestation increases the amount of carbon dioxide in the atmosphere, contributing to climate change.

• Deforestation decreases the amount of carbon dioxide in the atmosphere, reducing climate change.

What are some ways to reduce carbon dioxide emissions in order to mitigate the effects of the carbon cycle on climate change?

• Increasing coal consumption

• Transitioning to renewable energy sources, improving energy efficiency, promoting sustainable transportation, implementing carbon capture and storage technology, and protecting and restoring forests.

• Encouraging deforestation

• Using outdated and inefficient technology
