Textbook Question
Chapter 24, Problem 2CT
The use of off-road recreational vehicles may double in the next 20 years. Enthusiasts would like increased access to government-owned deserts like the one shown in Figure 24.1 A. Some argue that deserts are the perfect places for off-roaders because “there’s nothing there.” Explain whether you agree, and why.

Do you think oil drilling should be permitted in the Arctic National Wildlife Refuge? Describe it's pros and cons.
NASA describes desertification as the wearing down of the land, a reduction in land productivity that may not be reversible. This means the land cannot
support the same plant and animal life as it could in the past. Desertification is often caused or exacerbated by humans as they mismanage the land while
growing or harvesting a natural resource.
Question: Human mismanagement/abuse of land can happen in many ways. Please choose the 2 options below that do NOT represent causes
of desertification due to land mismanagement.

Many argue that government freshwater subsidies promote the expansion of productive farmland, stimulate local economies, and help to keep food and electricity prices low. Do you think this is reason enough for governments to continue providing subsidies to farmers and cities? Why or why not? Incorporate what type of feedback would be needed to garner enough legislative support for your position.

Which of these things do you already do or plan to do?arrow_forwardA group of researchers are assessing energy availability in a terrestrial ecosystem. The image shows the food web for this ecosystem. They set up three plots and assess the biomass of producers, primary consumers, and secondary consumers. Rabbits and grasshoppers feed on ground cover plants that grow on the forest floor. Plot 1 is composed of mature hardwood trees, and only 25% of the sunlight reaches the shrubs and grasses compared to plots 2 and 3, which have fewer trees and allow more sunlight to reach the forest floor. Based on the food web shown here, which of the following best describes how the reduction in sunlight to the forest floor would impact the number of primary consumers (squirrel, grasshopper, rabbit, and deer) in plot 1 compared to the other plots? A - Plot 1 will show an increase in deer only because they feed on trees. B - Plot 1 will show a decrease in squirrels and rabbits, while deer and grasshoppers will increase. C - Plot 1 will show a decrease in rabbits and…arrow_forwardLand Use in the United States Parks and preserves 13% Urban land 6% Cropland 20% Other 7% Forest land 28% Rangeland and pasture 26% What percentage of land is being used by humans to raise crops & graze livestock?

True Falsearrow_forwardInterpreting Data In a classic study, John Teal measured energy flow in a salt marsh ecosystem. The table below shows some of his results. Form of energy Kcal/m?/yr Efficiency of energy transfer (%) Sunlight 600,000 n/a Chemical energy in producers Chemical energy in primary consumers 6,585 81 Data from: J. M. Teal, Energy Flow in the Salt Marsh Ecosystem of Georgia. Ecology 43: 614-24 (1962). a. Calculate the efficiency of energy transfer by the producers. That is, what percentage of the energy in sunlight was converted into chemical energy and incorporated into plant biomass? b. Calculate the efficiency of energy transfer by the primary consumers. What percentage of the energy in plant biomass was incorporated into the bodies of the primary consumers? What became of the rest of the energy? c. How much energy is available for secondary consumers? Based on the efficiency of energy transfer by primary consumers, estimate how much energy will be available to tertiary consumers. d.

(g) In addition to improving air quality and reducing energy usage in cities, increasing the amount of vegetation can decrease urban runoff.
