It is not so difficult to imagine what it means to feedon the organic molecules that living things produce. Thatis, after all, what we do. But what does it mean to “feed” onsunlight, as phototrophs do? Or, even stranger, to “feed” onrocks, as lithotrophs do? Where is the “food,” for example,in the mixture of chemicals (H2S, H2, CO, Mn+, Fe2+, Ni2+,CH4, and NH4+) that spews from a hydrothermal vent?
Describe the journey starting as a molecule of CO2 in the atmosphereof the top layer of the bottleDescribe at least 3 transformations and the organisms involved .
The burning of fossil fuels releases CO2 into the atmosphereand is detrimental to the Earth’s ecosystems. Explain whythe use of biofuels, which also release CO2, is an improvement over fossil fuels.
Endothermics have constant core temperatures because of...a. temperature fluctuations in the environmentb. heat-producing cellular reactionsc. adaptations such as skin and furd. all the reasons cited abovee. none of the reasons cited above (not a graded question)
Fossil fuels are still relatively cheap toextract and produce. What technologyadvances do you think are needed to makebiodiesel cheaper to produce?
Explain how nitrogen gets from the atmosphere into aplant’s body.
Global Carbon Dioxide Cycling Expressed as Human Equivalents If 3 x 1014 kg of CO2 are cycled through the biosphere annually, how many human equivalents (70-Kg people composed of 18% carbon by weight) could be produced each year from this amount of CO2?
In biofuel production, plants are grown in order to create fuels thatare eventually burned in vehicles like automobiles. Overall, does theprocess of biofuel production add carbon dioxide to the atmosphere,remove it, or both?
Humans have the most urgent need for a continuoussupply of ________.a. foodb. nitrogenc. oxygend. water
When animals oxidize stored fat, they produce metabolic water.Even though the production of metabolic water from stored fatfollows principles of chemical stoichiometry, the net gain of waterthat animals realize from the oxidation of stored fat depends onthe humidity of the atmosphere. Explain why. Does the net gainincrease or decrease as the atmosphere becomes more humid?
Explain how living things recycle oxygen in Earth’s atmosphere.
Many people who want to reduce their ecological footprinthave focused on how much energy is expended (and howmany climate-warming greenhouse gases are emitted) intransporting food from its place of production to its place ofsale. The typical grocery store item is shipped by truck, air,and/or sea for many hundreds of miles before reaching theshelves, and this transport consumes oil. This concern over“food-miles” has helped drive the “locavore” movement tobuy and eat locally sourced food.However, food’s transport from producer to retailer, asmeasured by food-miles, is just one source of carbon emissionsin the overall process of producing and delivering food. In2008, environmental scientists Christopher Weber and H. ScottMathews conducted a thorough life-cycle analysis (p. 400) ofU.S. food production and delivery. By filling in the table below,you will get a better idea of how our dietary choices contribute toclimate change. After measuring mass, energy content, and dollar valuefor each…
