Ecology Unit Test is tomorrow. Finish your study guide tonight and read it over. Be sure to bring it with you tomorrow for credit. Answers shown below include many questions we did not cover in class.
Ecology Study Guide
1.What
is an introduced species? Define and give an example:
Species now found outside of their
normal range.
Ex: zebra Musselmussel
2. Are
introduced species bad? Why or why not? Consider
what could happen if you released the following animals into
the wild:
a.
your house cat
BAD: could wipe other species from their
habitat
(disease, competition, hunt and kill), cruelty – could die
from hunger
or predators or disease or accident.
GOOD: easy way out (LAZY); could
be food for
consumers in the
habitat
b.
your Burmese Python
Same, much more effective at killing all
other
animals
3.
What factors
influence the survival of any introduced
species? Name
at least 3:
Adequate prey (food), water,
climate,
(temperature),
shelter
,
competitors, predators in
new habitat.
4. James,
a boy from Kenya, spoke about the Nile Perch &
results/ consequences (both
intended & unintended) of
introducing the species. Describe:
a. Three advantages of introducing Nile Perch
into Lake
Victoria:
More jobs, money, and fish (food)
b. Three disadvantages of introducing Nile
Perch into Lake
Victoria:
Loss of independent small businesses,
wiped out
smaller fish species (Cichlids), perch overpopulated,
more
competition, fewer kinds of fish, and wrecked the
food chain, allowed algal
blooms.
c. Knowing what we know now, if you had had
the choice,
would you have introduced the Nile Perch into Lake
Victoria? Write about a trade-off (compare at least one
advantage and at least one disadvantage to make that
choice
5.
What is Ecology?
Study
of relationships between living organisms &
the physical environment.
6.
What
does classification show and what factors is classification base on? See p.
E-19
Grouping organisms based on relationships between similar organisms, based on genetic makeup and similar physical structures.
7.
What is an Invertebrate? Animal without a spinal cord or backbone
8.
Classification Levels: A. ex: domains contain 5 Kingdoms;
B. Kingdoms
contain 35 phyla
C. Phyla
contain many classes
D. classes
contain
many Genuses
E. Genuses
contain many species
9.
What is a
species? Define & give an example:
Species
- level of biological classification made up of organisms or populations capable of
interbreeding. Ex: homo sapiens; brown snake.
10. Explain
photosynthesis, including:
a.Who
does it? (role)
Producers
b.Who
does it? (which kingdom)?
Plants
c.What are
the starting materials (inputs or reactants)?
CO2
+
H2O + sunlight
d.
What are
the ending materials (outputs or products)?
food (sugar) + O2
