Textbook Question
Chapter 24, Problem 4AWK
In the 1970s, the Black Forest of Germany experienced a period when the number of trees dying in the forest increased substantially in a relatively short period of time. In addition, fish began to die in some of the lakes in the region. What could have caused these deaths to occur simultaneously in two very different habitats?

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?
Why is regular burning (thru natural fires) an important part of maintaining the health of grasslands and coniferous forests? Identify benefits that are specific to each biome. Also, discuss how suppressing fires could negatively affect each system.
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.

- In many areas, forests are burnt to clear land for agriculture. Explain how this method of deforestation would alter the carbon cycle.arrow_forwardAir and water pollution are environmental problems that has resulted to depletion of wildlife species and may lead to extinction. What would be the possible solution and the role in the suggested solution?arrow_forwardDeforestation is the clearing of Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world's land area, but swaths the size of Panama are lost each year. Deforestation on such a large scale has a dramatic effect on the carbon cycle. Which of the following describes the effect large scale forest clearing will have on the carbon cycle?arrow_forward
- 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)arrow_forwardA large hurricane destroys a coastal forest, leaving only a bare, muddy seashore. The following year, ecologists find small sea grasses growing in the area. What will an ecologist EXPECT to observe in later years? This ecosystem will be converted into a grassy beach. Eventually small shrubs will begin to grow, and after a number of years, trees will grow in this area again. Nothing will happen because the hurricane destroyed the ecosystem.arrow_forwardMost humans would agree that they wouldn’t want to intentionally destroy something useful or valuable, and most agree that rainforests are valuable. If this is so, what is driving humans living in or near rainforests to destroy their own ecosystems?arrow_forward
- What are the importance of a biodiverse ecosystem of birds in a mountain influence other organisms in the same mountain?arrow_forwardIf only one half of the flora in the world existed in 2110 (perhaps due to deforestation), what do you predict the atmospheric carbon level would be ? How would you change the simulation to reflect this? What is the relationship between increased carbon in the ocean and increased carbon in the soil? How else might carbon be transferred to soil? Using the data generated by the simulation, determine the mathematical relationship between the percentage increase in fossil fuel consumption and the increase in atmospheric carbon. Is the relationship linear?arrow_forwardHow would loss of fungi in a forest effect biogeochemical cycles in the area? a. Nitrogen could no longer be fixed into organic molecules. b. Phosphorus stores would be released for use by other organisms. c. Sulfur release from eroding rocks would cease. d. Carbon would accumulate in dead organic matter and waste.arrow_forward
- Where is exponential growth by a plant population more likely—in an area where a forest was destroyed by fire or in a mature, undisturbed forest? Why?arrow_forwardWhich of these hypotheses does not explain why increased CO2 levels in the atmosphere could cause a decrease in the productivity of some crops because of changes in climate? A) There could be increases in average winter temperatures that reduce the growth of crops. B) There could be decreases in precipitation in some regions that reduce growth in some crops. C) There could be shifts in the ranges of some important species in the community, such as pollinators, that cause reduction of growth in some crops.arrow_forwardPart 2.Discuss and answer these questions:1. Is the natural breeding of animals in zoos and game parks agricultural activity?2. Is ocean fishing agricultural activity?3. Is palm plantation agricultural activity? Describe the accounting treatment for biological assets and agricultural products in oil palm plantationsarrow_forward
