- In biofuel production, plants are grown in order to create fuels thatare eventually burned in vehicles like automobiles. Overall, does theprocess of biofuel production add carbon dioxide to the atmosphere,remove it, or both?How does the combustion of fossil fuels influence our planet? Be sure to explain how the following are directly related to the combustion of fossil fuels: acid deposition, sea level rise, global climate change, greenhouse gasses and one other event of your choosing.Which of the following processes of the carbon cycle involves the incorporation of the carbon in shells of marine organisms into the Earth’s crust? A. Burning of fossil fuels B. Photosynthesis C. Sedimentation D. Aerobic respiration
- If no photosynthesis or biological pump operated in the ocean, what would likely happen to the concentration of atmospheric carbon dioxide?Which of the following processes increase(s) the amount of atmospheric carbon in the carbon cycle? (a) photosynthesis (b) cellular respiration (c) combustion (d) a and c (e) b and cHow does the processes of cellular respiration impact the global carbon cycle? Group of answer choices It returns CO2 to the atmosphere that is breathed out by animals. It leads to the conversion of Ammonium into Nitrate. It removes CO2 from the atmosphere. It adds CO2 to the inaccessible reservoir.
- Carbon dioxide in the atmosphere traps heat. Scientists are concerned that too much carbon dioxide is being released into the air by human activity. Using your knowledge of the carbon cycle, where do you think this carbon dioxide is coming from? List at least three possible sources of human-related carbon dioxide production. Carbon dioxide is produced by the burning of fossil fuels.Forests take in carbon dioxide from the air, thus it is called “carbon dioxide sinks” or “carbon sinks”.- What is the use of carbon dioxide in the forests? Explain.Why is carbon dioxide the focus of so much attention regarding climate change? What are the main sources of carbon dioxide in the atmosphere and what can we do to reduce the amount of carbon dioxide in the atmosphere? Bring into your discussion the carbon cycle, a discussion of Venus and Mercury, the evidence for human impact on carbon dioxide levels in the atmosphere and its impact on climate (refer to any graphs you need to), and ways in which scientists have recommended limiting climate change.
- All of the following processes are involved in the carbon cycle except:a. photosynthesisb. cell respirationc. evaporationd. decompositionHow is atmospheric carbon dioxide different than carbon emissions?Considering the extra carbon created by humans, how might it be possible (or is it?) to generate more means of recycling carbon?
