6

7 Primary succession in a terrestrial community is similar to ______ lenthic bodies of water a.Oligotrophic b.Eutrophic c.Limnetic d.Benthic e.littoral

8 Draw a food chain of an aquatic life zone. Include at least three specific types of aquatic organisms.

9 Pollution form which of the following is an example of point source pollution? A- fertilizers from agricultural fields B- runoff from Midwestern farms C- oil spills from leaky pipelines D- pesticides from farmlands E- smoke from an industrial plant’s smokestack

10 An example of tragedy of the commons would be A- grazing cattle on private land B- emitting sulfur dioxide into the atmosphere C- harvesting lumber on private land D- fish in a stock tank E- gathering fruit from an orchard

11 Which of the materials below is an example of high quality matter? A- natural gas B- oil on the ocean floor C- Nitrogen in the atmosphere D- recyclable materials in a land fill E- coal found deep under ground

12 Which organism has a type 1 survivorship curve? A- a fish B- a bird C- insects D- redwood trees E- butterflies

13 The warming of the oceans that causes less carbon dioxide to be soluble in them and,at the same time, leaves more carbon dioxide in the atmosphere that causes an increased warming of the atmosphere is an example of a A- paradigm shift B- negative feedback loop C- positive feedback loop D- scientific principle of sustainability E- natural law

14 Organisms live within a range of tolerance that determines where they live. Which of the conditions below is not a range of tolerance? A- trout populations live in areas with a low temperatures B- coral polyps need a symbiotic algae living within them C- desert cacti thrive in areas with low levels of rain D- blue crabs in an estuary can tolerate a wide swing of temperature and salinity E- Royal ferns require moist areas and are only found in wetlands

15 As a country goes thought the demographic transition, the greatest rate of population growth takes place during which phase? A- preindustrial B- Pretransitional C- transitional D-industrial E- postindustrial

16 A one hectare pond is sampled in early September. The sample yields 1 small catfish as well as 14 invertebrates that represent 10 species. Which of the following can be estimated from the sample for the invertebrates in the pond? A- species richness B-pond productivity C- species distribution in the pond D- degree of disturbance C- stability of the ecosystem

17 Which of the following is the correct order of soil particles in order of increasing size A- Clay- sand –silt B-Clay- silt- sand C- Sand- clay- silt D-Sand- silt- clay E- Silt- clay- sand

19 Two varieties of peppered moths (a white moth and a black moth) were dominant in the northern British countryside during the early industrial age. Over time, the white lichen on which the moths would sit began to darken due to the effects of air pollution. Gradually, the white color phenotype was removed from the population until the black color phenotype dominated. This case study is best an example of. a.Directional selection b.Disruptive selection c.Stabilizing selection d.Sexual selection e.Artificial selection
