BIOL 355 Ecology Final Exam Review
1. Thank you for reading the syllabus! The answer to this "question" is..: cuttlefish
2. Our course is modeled after the Biological Hierarchy. Choose the correct or-
der, from the largest to the smallest level, of the Biological Hierarchy:: biosphere
ecosystem community population organism
3. Which of the following is an example of an emergent property of the Ecosys-
tem Level of theBiological Hierarchy?: Nitrogen cycling in an acidic bog
4. As a biologist interested in the effects of climate change, you are studying
the heat tolerance of ants. You hypothesize that there is an optimum temper-
ature at which ants function, as measured by their metabolic rates. To test
this, you place ants in chambers with different temperatures: 15C, 20C, 25C,
and 30C. This is an example of a experiment.: manipulative
5. As a biologist interested in the effects of climate change, you are studying
the heat tolerance of ants. You hypothesize that there is an optimum tem-
perature at which ants function, as measured by their metabolic rates. To
test this, you measure the metabolic rates of ants in locations with different
average daily temperatures: High temperature urban sites, mid-temperature
open field sites, and relatively cool shaded forested sites. This is an example
of a experiment: natural
6. As a biologist interested in the effects of climate change, you are studying
the heat tolerance of ants. You hypothesize that there is an optimum tempera-
ture at which ants function, as measured by their metabolic rates. To test this,
you create a program that simulates the metabolic rate of ants under varying
climate conditions. This is an example of a experiment.: mathematical
model
7. Which of the following is an emergent property of the Community Level of
the Biological hierarchy?: Sea urchin populations increasing with a decrease in otter populations
8. Which of the following statements about thermal properties of water is
TRUE?: The high specific heat of water allows water to resist changing states of matter
9. Which of the following properties of water most contributes to sea level rise
,as a result of increased mean global temperatures?: Thermal expansion of liquid water
10. Which of the following is an adaptation as a response to the high viscosity
of water?: Large appendages of small zooplankton
, 11. There are many properties of water that favor the presence of life. Which of
the following statements about the pH of aquatic environments is FALSE?: The
pH of water never favors life, but is a challenge to organisms in aquatic environments.
12. In general, what environment is limited in CO2?: The boundary layer of a submersed
plant; Calcareous fens
13. Which of the following is TRUE regarding antifreeze proteins in Notothe-
nioid fish?: They lower the internal freezing point of the fish, resulting in fish that cannot freeze; The proteins
binds to ice crystals and prevents the crystals from growing
14. Which of the following is the primary cause for limited CO2 in aquatic
environments?: CO2 readily reacts with water and is converted to carbonic acid
15. Countercurrent exchange in the gills of a fish : maintains a concentration gradient
that enhances dittusion
16. An agroecologist is a scientist who studies ecological principles and ap-
plies them to agricultural processes. One aspect of interest is the amount of
irrigation needed to sustain crops without wasting water. The agroecologist
decided to test the of the soil by monitoring when corn could
no longer extract water from the soil: permanent wilting point
17. Which of the following is NOT a distinct characteristic of serpentine soils?-
: Low percentage of organic matter
Low Ca:Mg
Limited nitrogen availability
High concentrations of heavy metals
18. What conditions can lead to limited nutrient availability for plants?: Limited
decomposition rates
Rapid decomposition rates
Sandy, porous soils
Soils low in organic matter
19. Which of the following is an example of acclimation?: Succulents evolved stomata that
close during hot, dry parts of the day
20. Imagine a species of palmetto that has three genotypes:1. Short and
shrub-like, found in dry, scrubby habitats.2. Tall and tree-like, found in coastal
wetlands3. Somewhat tall but still shrub-like, found on the coastal sand
