Textbook Question
Chapter 20, Problem 3MCQ
What is the connection between agriculture in the midwestern United States and the Gulf of Mexico’s “dead zone”?
| a. | Pesticides from farmlands are killing ocean life. |
| b. | Nutrient enrichment causes oxygen depletion in the waters of the Gulf. |
| c. | River sediments block out the light needed for photosynthesis in the Gulf. |
| d. | Farmlands use up all of the nitrogen in the water, so the Gulf waters are starved for nutrients. |

The carbon cycle is nature’s way of reusing carbon atoms, which travel from the atmosphere into organisms in the earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. Evaluate the carbon cycle model. Predict the changes that would occur within the carbon cycle as a result of deforestation. Choose all that apply
A) there would be less carbon in the soil due to the loss of trees
B) there would be an increase in atmospheric carbon due to less plant respiration
C) there would be an increase in atmospheric carbon due to decreasing photosynthesis
D) there would be an increase in oceanic carbon due to increasing atmospheric levels
E) there would be an increase in atmospheric carbon due to increased emissions from burning of trees
If decomposers were removed
from an ecosystem, which of
the scenarios below would
occur?
A. The number of plant species would
increase due to the increased space available.
B. The number of animals would decrease
due to the lack of plant life.
C. The ecosystem would collapse due to the
lack of nitrogen and carbon available to
producers.
If there are many greenhouse gases, why is only carbon dioxide considered a cause of global warming?a. The other gases do not cause global warming.b. It isn’t. Scientists are concerned about other causes; for example, release of methane from melting permafrost could have significant effects on global warming.c. Other gases occur in such low quantities that they have little effect on the climate.d. Carbon dioxide is the only gas that absorbs long-wavelength infrared radiation.

- What would most likely happen if too many nutrients entered an estuary? O a. Algal blooms would decrease, leaving few food resources for fish. O b. Nutrients would sink to the bottom, increasing soil deposition O C. Nutrients would be used up by the fish and plants, keeping the estuary in balance. d. Algal blooms would lower dissolved oxygen levels, causing fish to suffocate. O e.

A.Energy flow reaches an equilibrium within ecosystems such that every trophic level has the same amount of energy. B. Because forests have relatively few large trees which support numerous smaller organisms, they have less energy at the lowest trophic level than at higher trophic levels. C. Energy is recycled within ecosystems, moving from producers to consumers to decomposers and back to producers. D. Energy flows through ecosystems with some lost at every transition resulting in lower trophic levels always containing more energy than higher trophic levels. E. Aquatic ecosystems have more energy at higher trophic levels than at lower trophic levels, whereas terrestrial ecosystems have more energy at lower trophic levels.
