- What is the relationship between an increase in fossil fuel consumption and increased carbon in terrestrial plants? How might this change flora populations? What impact could twenty years at this level of consumption have on flora? What is the relationship between an increase in total carbon concentration (the smokestack) and increased carbon in the ocean surface? How might this change marine life populations? What impact could fifty years at this level of emissions have on marine fauna? On marine flora? In addition to circulating through the carbon cycle, where else might excess carbon be found? In fifty years, where would you be most likely to see excess carbon? Which areas are most highly (and quickly) affected by an increase in carbon emissions (and increase in fossil fuel consumption)? How would these effects manifest themselves? What are the dangers/benefits to these areas?INTERTRET DATA Scientists have compiled databases of large forest wildfires in the western United States and compared them to climate and land-surface data. Examine the graph showing wildfire frequency compared to average springsummer temperature. Do you see a correlation? If so, describe it. Based on these data, do you think that climate warming is causing more wildfires? Explain your answer.Which of the following is NOT a question suitable for scientific inquiry? Select an answer a Which fossil fuel is the dirtiest to burn? b Is it ethical to put heavily polluting industries in low-income neighborhoods? c Does the burning of fossil fuels contribute to global warming? d Does the use of renewable energy sources contribute to ozone depletion?
- Imagine a sealed terrarium containing a plant and a beetle. How does each organism provide resources for the other? Could each organism survive if it was the only living thing in the terrarium? Why or why not?One outcome of climate change will be a shift in where particular climate conditions exist (for instance, you will have to move further north if you want to stay in Chicago-like weather). In order to survive, some organisms may have to move. The movement rate of the climate and the movement rate of a species are described by Climate Velocity and Frame Shift Rate. Using the Sugar Maple tree as an example, describe what climate velocity and frame shift rate are AND how they can combine to force the sugar maple to go extinct. (If you do not properly use the terms Climate Velocity and Frame Shift Rate as part of your answer you are not going to get many points on this question)In three to five sentences, describe how the diagram of Earth’s carbon cycle demonstrates the interactions among the biosphere (plants), the lithosphere (ground), the atmosphere (air), and the hydrosphere (water).
- What effect does a high carbon level have on the deep ocean? Why might it be important to keep an eye on the deep ocean carbon levels?

The family would like to purchase some forested land in the Catskills, keeping the trees intact as an offset to the carbon dioxide they produce travelling each year. How much forest must they purchase? Use the following assumptions to measure the carbon offset provided by this intact forest. • The biomass of the forest increases at an annual rate of 2.8 × 105 kg/ha. • The forest biomass is 45% carbon by mass. • There are four people in the family. • 0.2 kg of CO2 is produced each mile per person on the flight. • The round-trip distance is 4,500 miles. • There are 2.47 acres in one hectare. 1. Calculate the mass of carbon, in kilograms, that is accumulated and stored in 1.0 ha of this forest in one year. 2. Calculate the mass of carbon, in kilograms, that is emitted by the family as a result of their round-trip flights to Costa Rica each year. 3. Calculate the number of acres of forest that must be…
- The carbon cycle is nature’s way of reusing carbon atoms, which travel from the atmosphere into organisms in the earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Evaluate the carbon cycle model. Predict the changes that would occur within the carbon cycle as a result of deforestation. Choose all that apply A) there would be less carbon in the soil due to the loss of trees B) there would be an increase in atmospheric carbon due to less plant respiration C) there would be an increase in atmospheric carbon due to decreasing photosynthesis D) there would be an increase in oceanic carbon due to increasing atmospheric levels E) there would be an increase in atmospheric carbon due to increased emissions from burning of treesGiven the information in the graph what conclusion can you make with respect to the relationship between climate change (increasing global temperatures) and the amount of carbon dioxide released into the atmosphere by land ecosystems? Explain, using information from the graph to support your explanation.a) Each trophic level, on average, will move 10% of the energy tied up in molecules to the next trophic level. How much of the energy from the sun is actually brought in to the first trophic level? b) When the producers convert energy and tie it up in the first trophic level, it is brought in as heat. True or false? c) Which of the following are true about ecosystems? Check all that apply. They contain both living and nonliving components.They contain both living and nonliving components. There is a transfer of energy through the system and some energy is lost as heat energy.There is a transfer of energy through the system and some energy is lost as heat energy.
