BSC 196 Exam #4 Q & A:
1. Which level of ecological study focuses on interactions between species?
a. Organismal ecology
b. Population ecology
c. Community ecology
d. Ecosystem ecology
e. Global ecology
2. Why are polar regions cooler than the equator?
a. The polar atmosphere is thinner
b. The poles are father from the sun
c. The poles are permanently tilted
d. Solar radiation strikes the poles at a lower angle
e. None of the above
3. Why do regions of heaviest rainfall occur at the equator, whereas deserts tend to be
distributed at approximately 30o latitude north and south?
a. Cool, moist air masses from the poles move along the surface, releasing
precipitation along the way to the equator, where they are heated and dried
b. The greater solar radiation at the equator cause air masses to rise and release
water, whereas dry, descending air masses create arid climates at 30o north
and south
c. There are fewer mountain ranges at the equator, resulting in fewer rain-shadow
d. A greater number of lakes are distributed along the equator, resulting in higher
rates of evaporation
e. None of the above
4. Why is the climate drier on the leeward (downwind) side of mountain ranges?
a. There are fewer lakes on the leeward side of mountain ranges
b. Air pushed by the wind on the windward side is forced to rise, cool, condense,
and drop its precipitation, leaving drier air to descend the leeward side
c. Deserts create dry conditions on the leeward side of mountain ranges
d. Solar radiation hits the leeward side of mountain ranges at a more direct angle,
resulting in a higher rate of evaporation
e. None of the above
5. Which two climatic factors are included in a climograph to distinguish different
terrestrial biomes?
a. Wind and fire
b. Temperature and wind
c. Temperature and precipitation
d. Sunlight and wind
e. Fire and precipitation
6. Which is the largest terrestrial biome?
a. Tundra
b. Northern coniferous forest

7. In aquatic biomes, the pelagic zone comprises the , whereas the benthic zone
comprises the .
a. Entire body of water; bottom sediments
b. Neritic and oceanic zone; aphotic zone
c. Photic zone; aphotic zone
d. Bottom sediments; detritus
e. None of the above
8. Seasonal turnover in lakes occurs:
a. When the surface water becomes warmer than the bottom water
b. When the layers separated by the thermocline attain the same temperature
c. During the hottest days of summer and the coldest days of winter
d. Only when winds exceed 30 miles per hour
e. Only during periods of heavy rainfall
9. What is a defining feature of estuaries?
a. Wet habitat along lakes and rivers that is periodically flooded
b. Transitional water bodies of variable salinity where rivers merge with oceans
c. Areas off the shores of oceans that are periodically submerged and exposed by
d. Coral reefs
e. Deep-water vents
10. Coral reefs are formed by which of the following animal groups?
a. Porifera
b. Cnidarian
c. Annelida
d. Mollusca
e. Arthropoda
11. In which zone of a lake are you likely to find invertebrate communities?
a. Benthic zone
b. Photic zone
c. Neritic zone
d. Pelagic zone
e. Abysmal zone
12. Which of the following would constitute dispersal?
a. A natural range extension
b. A bird species colonizing a new island
c. A species deliberately introduced into a new habitat
d. A species accidentally introduced into a new habitat
e. All of the above
13. Which of the following would represent an abiotic factor affecting the distribution of
a. Predation
