Some analysts argue that in order to continue usingoil at the current rate, we must discover and add toglobal oil reserves the equivalent of two new SaudiArabian reserves every 7 years. Do you think this ispossible? If not, what effects might the failure to findsuch supplies have on your life and on the lives ofany children and grandchildren that you might eventually have?

Stellvester Ajero is a farmer who raises deer in his ranch. He has 100 female deer age 3–15 months. The deer require 22 MJ of metabolizable energy per day during the spring months. The deer are being fed a mixture of 50% wheat and 50% silage. The wheat contains 85% dry matter (DM) and has 12.5 MJ metabolizable energy per kilogram of DM. The silage has 30% dry matter and 10.5 MJ metabolizable energy per kilogram of DM.a) How many kilograms of feed are required per day to feed the 100 deer?b) Calculate the energy (in MJ) converted to body tissue on a daily basis. Assume that 19% of the feed consumed is excreted as undigested material. Of the remaining 81% that is digested, 78% is used in generating metabolic waste products and heat. The remaining is incorporated into tissue.
The organophosphate Azinphos-methyl has a96-hour LC50 value of 3 ppb for rainbow trout. Inan unfortunate incident, 200 g of this pesticidewas sprayed on a field, and a subsequent heavyrainfall washed 35% of it into a nearby lakehaving a surface area of 30,000 m2and anaverage depth of 0.5 m. Would the pesticideconcentration in the lake water have beensufficient to kill a significant fraction of therainbow trout in the lake?
What is the range of values for percentage of emissions from transport of food to retailers (delivery)? Weber and Mathews found that 83% of food’s total emissions came from its production process on the farm or feedlot. What do these numbers tell you about how you might best reduce your own footprint with regard to food?
Form of energy Kcal/m^2/yr Efficiency of energy transfer (%) Sunlight 600 000 n/a Chemical energy in producers 6 585 Chemical energy in primary consumers 81 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? 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? 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. Draw a pyramid of production for the producers, primary consumers, and secondary consumers for this ecosystem (see example in your textbook).
11) The chart below compares the greenhouse gas emissions of several fuel sources. Greenhouse Gas Emissions of Fuel and Energy Sources Sugarcane Ethanol Cellulosic Ethanol Fuel > Gasoline Corn Ethanol Energy > Source Fossil Fuels Biomass Biomass Biomass Source: Adapted from http://energy.itgoverns.com An accurate prediction that could be made regarding the information shown in the chart is that A) fossil fuels emit the least amount of greenhouse gases the use of biomass-based fuels instead of fossil fuels will greatly decrease the production of greenhouse gases B) C) the use of any one of the ethanol sources for fuel will each produce more greenhouse gases than the use of gasoline for fuel D) a total change from gasoline to ethanol as a fuel would have no effect on greenhouse gas emissions Greenhouse Gas Emissions
