E many nutrients are destroyed by high temperatures in the tropics. C The carbon cycle is a localized cycle that primarily reflects the burning of fossil fuels. Energy can be released through the and of sulfur compounds e. D Matter can be converted into energy; energy cannot be converted into matter.
The primary reason for this pattern is that A secondary consumers and top carnivores require less energy than producers. D A and C only E A, B, and C 67 Which of these are two major sources of nitrate pollution in rivers? Carbon, nitrogen, and oxygen cycles are biogeochemical cycles.

Question 10 0 out of 2 points Which of the following would be most likely to occur in the year after Congress, in an effort to increase tax revenue, passed legislation that forced companies to depreciate equipment over longer lives? Carbon is held for a relatively short time in plants and animals in comparison to coal deposits.
Carbon, nitrogen, and oxygen cycles are biogeochemical cycles. B Some gypsy moths cannot feed and thus die because others moths have defoliated the trees in the area. The flow of energy in an ecosystem is an open system; the sun constantly gives the planet energy in the form of light while it is eventually used and lost in the form of heat throughout the of a food web. B increased worldwide standing crop biomass. C Energy can be converted into matter; matter cannot be converted into energy.
However, for valuation purposes we need to discount cash flows, not accounting income. C It has the greatest total area. The rock cycle is a biogeochemical cycle. D Only a small portion of the energy captured by producers is transferred to consumers. Biogeochemical cycles always involve hot equilibrium states: a balance in the cycling of the element between compartments.
E top carnivores and secondary consumers have a more general diet than primary producers. Question 4 0 out of 2 points Which of the following could explain why a business might choose to operate as a corporation rather than as a sole proprietorship or a partnership? The primary reason for this pattern is that A secondary consumers and top carnivores require less energy than producers. A the energy contained in the standing crop B the energy used by heterotrophs in respiration C the energy used by autotrophs in respiration D the energy fixed by photosynthesis E all solar energy How is it that the open ocean produces the highest net primary productivity of Earth's ecosystems, yet net primary productivity per square meter is relatively low? A Predators are sparsely distributed. C Global warming could have significant effects on United States agriculture. A the ecosystem's rate of primary production B the production efficiency of the ecosystem's consumers C the rate of decomposition in the ecosystem D the trophic efficiency of the ecosystem E the location of the nutrient reservoirs in the ecosystem Share the flashcard by embedding it on your website or blog Exam Note Cards Ch 54 » Flashcards Online. Gaseous elements cycle more quickly than elements without a gaseous phase. C Chemoautotrophic prokaryotes near deep-sea vents are primary producers.
D Nutrient cycling rates tend to be limited by decomposition. B at each step, energy is lost from the system as a result of keeping the organisms alive. B Predators have relatively small population sizes. Other things held constant, which of the following will occur as a result of this Congressional action? D grains raised for feed must be fortified, and thus require additional nutrients. Both checks were issued to D.
Carbon, nitrogen, and oxygen cycles are bio-geochemical cycles. If you wanted to investigate this, one reasonable avenue would be to A follow whale migrations in order to determine where most nutrients are. E Grasshoppers in a corn field are killed by a viral infection Which of the following statements about energy flow is incorrect? C organic matter decomposes more rapidly and plants assimilate soil nutrients more rapidly in the tropics. C the ratio of net production at one trophic level to the net production at the level below, expressed as a percentage. B most of the energy in a trophic level is incorporated into the next higher level.
Which of the following statements about biogeochemical cycles is not true? Question 11 2 out of 2 points Aubey Aircraft recently announced that its net income increased sharply from the previous year, yet its net cash flow from operations declined. These cycles include both the living biosphere and the nonliving lithosphere, atmosphere, and hydrosphere. B phytoplankton have a relatively short life cycle. Generally, reservoirs are abiotic factors whereas exchange pools are biotic factors. E phosphate is the limiting nutrient in these waters.
Flashcards vary depending on the topic, questions and age group. E Matter is used in ecosystems; energy is not To recycle nutrients, the minimum an ecosystem must have is A producers. Therefore it is important that the investors use the method that provide more relevant information and also correct valuation. In the , sulfur can be forever recycled as a source of energy. A Polar bears can provide more food for people than seals can.
E Grasshoppers in a corn field are killed by a viral infection. B the nutrients that enter the plants grown on those lands do not return to that soil. At the reunion your brother gave you a check for the stock and you gave your brother the stock certificates. D A and B only E A, B, and C Which of the following statements is are true? B observe Antarctic Ocean productivity and compare that to other areas. Question 12 0 out of 2 points Which of the following factors could explain why Regal Industrial Fixtures had a negative net cash flow last year, even though the cash on its balance sheet increased? Question 25 2 out of 2 points Arshadi Corp. The rock cycle is a biogeochemical cycle.
