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
