Carbon cycle

What natural process releases carbon dioxide into the atmosphere?

• Soil erosion and deforestation

• Respiration and decomposition of organic matter

• Combustion of fossil fuels

• Photosynthesis and water evaporation

What is the process by which plants absorb carbon dioxide?

• Evaporation

• Photosynthesis

• Transpiration

• Cellular Respiration

Which organisms decompose organic matter releasing carbon dioxide into the soil?

• Plants and animals

• Microorganisms such as bacteria and fungi

• Water and air

• Rocks and minerals

What geological process involves the release of carbon stored in sedimentary rocks?

• Tectonic subduction

• Wind erosion

• Nuclear fusion

• Chemical weathering

What role do the oceans play in the carbon cycle?

• The oceans convert all carbon into greenhouse gases

• The oceans absorb carbon dioxide from the atmosphere and store it in the form of organic matter, helping to regulate the balance of carbon in the atmosphere.

• The oceans have no impact on the carbon cycle

• The oceans emit large amounts of carbon dioxide into the atmosphere

What natural process converts carbon into fossil fuels such as oil and natural gas?

• Mineralization process

• Evaporation process

• Crystallization process

• Fossilization process

What is deforestation and how does it affect the carbon cycle?

• Deforestation increases the forests' capacity to absorb carbon dioxide

• Deforestation affects the carbon cycle by reducing the forests' capacity to absorb carbon dioxide from the atmosphere, contributing to the increase of greenhouse gases and climate change.

• Deforestation decreases the amount of greenhouse gases in the atmosphere

• Deforestation has no impact on the carbon cycle

What is photosynthesis and how is it related to the carbon cycle?

• Photosynthesis is the process by which plants and other organisms convert sunlight into chemical energy to produce their food. It is related to the carbon cycle because during photosynthesis, plants absorb carbon dioxide (CO2) from the air and use it to produce glucose, releasing oxygen as a byproduct. This process helps regulate the level of CO2 in the atmosphere and is essential for maintaining the balance of the carbon cycle on Earth.

• Photosynthesis is a process exclusive to animals

• Photosynthesis is a process that involves the absorption of water by plants

• Photosynthesis has no relation to the carbon cycle

What is cellular respiration and how does it influence the release of carbon dioxide?

• Cellular respiration only produces oxygen as a byproduct

• Cellular respiration produces carbon dioxide as a byproduct of glucose degradation in the Krebs cycle and the electron transport chain.

• Cellular respiration has no relation to the release of carbon dioxide

• Carbon dioxide is released during photosynthesis, not in cellular respiration

Why is the balance of the carbon cycle important for the environment?

• The balance of the carbon cycle regulates the amount of carbon dioxide in the atmosphere, which affects the greenhouse effect and climate change.

• The carbon cycle is not related to climate change

• The balance of the carbon cycle only affects animals, not the environment

• The carbon cycle has no impact on the environment
