Row 1, Col 1 Day-to-day conditions in Earth’s atmosphere, such as “sunny and humid,” describe What is WEATHER?

1,2 In Madagascar, several species of lemur eat bamboo, but each species specializes in one part of the bamboo— one species eats mature bamboo stalks, one species eats bamboo shoots, and one species eats leaves. This is an example of What is RESOURCE PARTITIONING?

1,3 “All the living things and their physical environment within a given area” best defines a.a community. b.an ecosystem. c.the biosphere. d.a population. b.an ecosystem.

2,1 Water with a salinity that is greater than fresh water but less than saltwater is classified as a.photic. b.aphotic. c.brackish. d.littoral. c.brackish.

1,4 In the western United States, at the southern edge of their range, moose are sometimes so severely infested with ticks that they die. The tick/moose relationship is best described as a.predatory. b.parasitic. c.symbiotic. d.mutualistic. b.parasitic.

2,2 The equation for determining population growth is a.(births + deaths) – (immigration + emigration). b.(births + emigration) + (deaths – immigration). c.(births + immigration) + (deaths – emigration). d.(birth s+ immigration) – (deaths + emigration).

2,3 The first level of all food pyramids a.consists of primary producers. b.consist of primary consumers. c.is chemosynthesis. d.is photosynthesis. a.consists of primary producers

2,4 When energy is transferred between trophic levels, the amount of available energy lost is about a.90 percent. b.50 percent.. c.25 percent. d.10 percent. a.90 percent.

3,1 Where rivers flow into the ocean, mixing fresh water with saltwater, brackish ecosystems occur which are called a.bogs. b.flood plains. c.estuaries. d.limnetic zones. c.estuaries.

3,2 Many bird species are territorial. In territorial birds species, what kind of population structure would you expect? a.uniform b.random c.clumped d. aging. a.uniform

3,3 A deer browsing on a shrub is an example of a.predation. b.parasitism. c.herbivory. d.symbiosis. c.herbivory.

3,4 A landslide causes part of a mountainside to fall away, leaving bare rock. In the years immediately following the landslide, the area will experience a.primary succession. b.secondary succession. c.tertiary succession. d.a climax community. a.primary succession.

4,1 In temperate rain forests, trees such as cedars and spruces, which do not lose their leaves at any time of year, are called a.coniferous. b.succulent. c.chaparral. d.deciduous. a.coniferous.

4,2 Pandas depend on bamboo. The amount of intact bamboo forest will help determine the a.biotic potential of the population. b. carrying capacity of the population. c.sex ratio of the population. d.limiting factor of the population. b. carrying capacity of the population.

4,3 A niche restricted by competition is a a.fundamental niche. b.realized niche. c.resource partitioned niche. d.displaced niche. b.realized niche.

4,4 If these are present in a new environment, a species is unlikely to become invasive. a.predators, parasites, and competitors b.cane toads, kudzu, and zebra mussels c.exotic species d.symbiotic and commensalist species a.predators, parasites, and competitors

5,1 Why do shorter trees and plants that make up the understory in tropical rain forests have large, flat leaves? a.to shade themselves from excessive sunlight b.to create habitat for forest insects c.to offer protection from rain d.to allow maximum surface for light absorption

5,2 Where wolves are reintroduced to Yellowstone National Park, the number of elk and other prey species within the park are a.a density independent factor. b.an example of biotic potential. c.a density dependent factor. d.a limiting factor. d.a limiting factor.
