UNIT 2 STUDY GUIDE: THE LIVING WORLD
Ch 4 FRQ Differentiate
between chemical and biological evolution.
What is natural selection’s role in biological evolution (
1) Scientist know a great deal
about the history of life on Earth and evolution. What is the single most significant
source of the information.
2) Did
3) What causes the genetic variation in populations?
4) Why is variation so important for natural selection
to occur?
5) What is coevolution?
6) Compare and contrast fundamental niche versus
realized niche.
7) Compare the size of the niches between generalist and
specialist species.
8) What is the effect of geographic isolation on
speciation rates?
9) Compare and contrast background extinction and mass
extinction.
10) What is genetic engineering? What are the concerns about it? Benefits?
11) What is biopharming?
Ch 5 FRQ What have
been Man’s impacts on each of the major terrestrial biomes?
1) Compare & contrast climate and weather.
2) What are the most important factors in determining a
region’s climate?
3) What influences global air circulation?
4) What do ocean currents do for the Earth?
5) What gases are considered greenhouse gases?
6) What effect do latitude and altitude have on biome
distribution?
7) Where on Earth (in terms of latitude) do we find
deserts (3 places)?
8) What adaptations do desert plants have for surviving
without water for long periods of time?
9) Grasslands are generally found on what areas of
continents?
10) Homo
sapiens first originated on what continent?
11) Rank the
biomes from greatest diversity to least diversity.
12) What are
the 3 names that are associated with the biome that has primarily conifer trees.
13) What significant
contributions do mountains make to continental ecosystems
Ch 6 FRQ How have
agriculture, global warming, controlling rivers with levees, and fishing
affected freshwater and marine aquatic biodiversity? Math to know: How to figure gallons of run-off from the number of inches of rain that fall per acre.
1) What are the 3 main zones of a river and
characterizes each?
2) What human activities are increasing the loss of
inland wetlands and mangrove swamps?
3) What ecological services do coral reefs perform?
4) What happens to coral reefs that are pushed into a
zone of intolerance for such factors as temperature and pollution levels?
5) Compare and contrast nekton, plankton (phyto- & zoo-), and benthos.
6) What are the life zones of lakes and oceans? What are their characteristics?
7) Where would you find the greatest net primary
productivity in the ocean?
Why? Lowest NPP? Why?
8) What are the ecological services provided by a
mangrove forest?
9) What abiotic factors are unique to the intertidal zone?
10) What part
of the earth makes the largest contribution of NPP and thus oxygen? Why?
11) What are
some major impacts that humans have had on marine ecosystems?
12) Compare
and contrast eutrophic and oligotrophic
lakes.
13) What
ecological services are performed by inland wetlands?
14) What have
humans done that have impacted freshwater systems the most?
15) What
factor is the single most important factor for determining what organisms live
in an aquatic system?
16) It’s weird, but deep dwelling fish
are very susceptible to depletion by over-fishing? Why?
17) Why are
coral reefs so vulnerable to extinction?
18) What is a watershed?
Ch 7
FRQ Of what
significance to a community are indicator species, keystone species, early
succession species (pioneer species), Predatory species, and invasive species. Math to know: a) How to use a proportion and cross multiply to solve for X and b) Rule of 70
1) What is the significance of each of the following
types of species to an ecosystem?
Native species, Invasive species, Foundation species, Keystone species,
& Indicator species
2) What is unique to each of the following
relationships? Predation, Commensalism,Mutualism, Parasitism, Competition
3) What ecological services are provided to an ecosystem
by alligators?
4) What is habitat fragmentation so detrimental to
species within an ecosystem?
5) Contrast species richness, species evenness, and
species diversity.
6) What is it about amphibians that make them so
vulnerable to extinction in the near future?
7) Why is it so important for scientists to identify the
keystone species of an ecosystem?
8) What is it that bioprospectors
do?
9) Compare and contrast primary and secondary
succession?
10) Differentiate the ecological
terms: stability, constancy,
inertia, resilience
11) What is
the relationship between biodiversity of an ecosystem and it NPP? Why?
12) What is
the relationship between the amount of niche overlap and degree of
competition? Why?
