- Which fraction of phosphorus is available for photosynthetic organisms to directly uptake and use? Organic phosphorus in detritus Absorbed phosphorus in clay Phosphorus in minerals in rocks Soluble phosphorus in waterA student is creating a model of the carbon cycle on a poster for a project at school. The student has cellular respiration and decomposition as labeled processes, with both of them showing a release of carbon dioxide into t atmosphere. According to the teacher's expectations for the project, the student must model an equal number of processes that sequester carbon out of the atmosphere as well. Which components should the student add to refi the model to include carbon dioxide sequestration? Select ALL that apply. A) B) 9) D) E) the process of photosynthesis occurring in forest plants the process of carbon dioxide dissolution into the ocean water The process of wildfires burning as trees and plants undergo combustion the process of anaerobic digestion of organic materials in rice fields or cow stomachs the process of fossil fuel combustion as coal, oil, and natural gas is used for fuel in energy conversions The long-ago deposited plant and animal remains, now buried, have been…Which of the following best describes how using fertilizer would affect the nitrogen cycle?

The atmosphere will cool. The atmosphere will warm. The carbon will have to precipitate out of the atmosphere. The carbon will be used in the nitrogen cycle. The carbon will be lost from the carbon cycle.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

- Chapter 10 of your textbook describes four biogeochemical cycles (some of which might also be called nutrient cycles) which carry elements and compounds essential to life on earth: the oxygen cycle, the carbon cycle, the nitrogen cycle and the phosphorous cycle. Read the sections in the textbook and refer to the diagrams for each of the cycles.These cycles are constantly going on around us. Think about how we are involved in these cycles. What parts of the major biogeochemical cycles do we witness or experience in our daily lives? Give one example per post or response. Think about where the element or nutrient may have come from or where it may go next and whether the process may have been affected by humans and human activities.A simple example (using the hydrologic cycle, which we studied in Chapter 7): Yesterday I was at the beach and witnessed rain falling into the ocean. This is part of the hydrologic cycle. Most of the rainwater probably came from evaporation of water from the…A family travels from New York City to Costa Rica three times a year for a vacation. 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. 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. Calculate the mass of carbon, in kilograms, that is accumulated and stored in 1.0 ha of this forest in one year. Show your work. 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. Show your work. Calculate the number of acres of forest…To generate biogas the required biomass resources must be on wet form, else biogas will not produce. How do you disagree or agree with this statement?
