BIO 220 Grand Canyon Week 1 Discussion 1
Choose an environmental
issue from your textbook, or from your own personal experience and explain how
this environmental issue directly affects you. What is the role of environmental
science in addressing this issue? What challenges do you believe are the
obstacles that would hinder the recommendations of environmental scientists to
address this environmental issue from being successfully implemented?

Select an example of a
global biome and an example of an ecosystem found in that global biome
(grassland, forest, desert). What kind of animals and plants would you expect
to make up that ecosystem? Provide one symbiotic relationship example within
your selected ecosystem (such as mutualism, commensalism, and predator prey).

View Biome Explorer
located in the Topic 2 materials. Choose a biome and a scenario and explain how
conservation genetics (refer to the lecture notes and textbook for examples)
could affect the survival of any of the species in the scenario. Other than the
factors identified in the media piece, what other factors can you identify that
contribute to the growth, stability, and decline of a species’ population?

Many people outside of
China believe that the country’s effort to reduce birth rates, through its
one-child policy, does not justify its methods. Do you agree? Can you think of
any future, unintended consequences for China as a result of adopting this
policy? Offer an alternative technique (one not currently used by China) to
reduce a country’s fertility rates that you believe would be less
controversial.

report from your local municipality. If you are unable to locate a recent
report from your municipality, use a report from a neighboring municipality.
Post a short description of what you found. What are your thoughts about your
tap water after reading the report you obtained? If you were in charge of your
local municipality, and the report indicate organic impurities within the water
supply, what technique(s) for water management (water pollution control,
remediation, or water legislation) would you employ to address this problem?

Method Matching Exercise Resource.”
GCU style is not required,
but solid academic writing is expected. You are not required to submit this
assignment to Turnitin,
Scientific Method Matching
Exercise Resource In Part I, match each example from Column 2 with the correct
step of the scientific method in Column 1. Explain the reasoning for your
choice in Part II. Part I
- a) A
scientist, based on his observation of the pond, believes that if a pond
is exposed to the waste of an industrial plant, then the growth of algae
will be accelerated.
- b) In her
laboratory, a scientist pours a vial of waste water, collected from the
industrial plant, and adds it to a dish containing pond water. A second
dish (the control dish), containing the same pond water, does not receive
the waste water sample.
- c) A
scientist wonders if the waste water emitted from an industrial plant is
accelerating the growth of algae in a pond.
- d) After
five days, the scientist measures the amount of algae present in each
dish.
- e) The
scientist submits his findings to a scientific journal.
- f) After the
data is collected, the scientist discovers that the dish containing both
the pond water and waste water had more than twice the amount of algae
than the control dish.
- g) A
scientist observes that a pond adjacent to an industrial plant has heavier
algae growth than ponds farther away.

2 Assignment
Biomes and Ecosystems
Details:
In this assignment, you
will be creating a trophic pyramid, also known as an “ecological pyramid,” for
a specific ecosystem, using the “Trophic Pyramid” template located in the Biome
Explorer at
.gcumedia.com/bio220/biome-explorer/v2.1/index.html”>http://lc.gcumedia.com/bio220/biome-explorer/v2.1/index.html.
Your completed trophic pyramid will be used to identify the trophic levels
within the food web, as well as their effects on the ecosystem. To complete
this assignment, do the following:
- Select an
ecosystem from an area of interest to you. When choosing an ecosystem, be
specific. For help differentiating between biomes and ecosystems, review
“Biomes, Ecosystems, and Trophic Levels.
2.Utilize credible sources
to select and research your chosen ecosystem, including the textbook and the
Internet (specifically, you may find the World Biomes page located at
.blueplanetbiomes.org/world_biomes.htm”>http://www.blueplanetbiomes.org/world_biomes.htm
helpful).
3.When researching your
selected ecosystem, give special attention to the plant and animals species
that inhabit that ecosystem. This information will be used to design the
ecological pyramid.
4.Refer to the “Trophic
Pyramid.” You will complete this template by entering the names of the species
that belong to the various trophic levels (Apex predator, tertiary consumers,
secondary consumers, primary consumers, and primary producers).
5.Refer to the text for
further information and an explanation of trophic levels.
Using your completed
trophic pyramid, answer the following questions in a Word document of at least
250-500 words:
- Of the
primary producers you selected, which one do you think has the biggest
impact on the ecosystem you researched? Explain.
2.”What species did you
select for the apex predator? Explain the importance the apex predator’s impact
on the other species in your tropic pyramid.
3.How did the amount of
energy gained compare to the amount of energy lost as heat at the 2nd–4th
trophic levels?
4.Referring to your
completed trophic pyramid template, select one species. If this species was
removed from your trophic pyramid, what would be the impact on the other
species of the ecosystem?
5.Can efforts to save a
species from extinction be successful if the focus of preservation is only on
that species? Explain your answer
6.Considering the amount
of energy required in producing animal-based foods and goods, should humans
change their habits so they consume products closer to the bottom of the
trophic pyramid? Provide rationale for your response.
This assignment requires a
minimum of two references to be included.
Prepare this assignment
according to the guidelines found in the GCU Style Guide, located in the
Student Success Center.
This assignment uses a
grading rubric. Instructors will be using the rubric to grade the assignment;
therefore, students should review the rubric prior to beginning the assignment
to become familiar with the assignment criteria and expectations for successful
completion of the assignment.
You are required to submit
the short answer portion of this assignment to Turnitin. Refer to the
directions in the Student Success Center. Only Word documents can be submitted
to Turnitin.
Submit both the Trophic
Pyramid and Word document to the instructor.
Biomes
Biomes are global
geographical areas that share similar climatic conditions.
Examples of biomes include
rain forests, tropical forests, tundra, grasslands, and deserts.
Ecosystems
Biomes contain ecosystems,
which are comprised of the living and nonliving components that occupy an
environment.
Examples of ecosystems
include coral reefs and ponds, tidal zones, oceans, coral reefs, kelp forests,
alpine meadows, and the Arctic and Antarctic Ocean.
Ecosystems consist of
various trophic levels, which comprise complex networks of food chains called
food webs. The more diverse an ecosystem, the healthier and more feasible it
is.
Differentiating the Two
The grasslands are a kind
of biome, while the African savanna or the Brazilian credo are both ecosystems
found within the grassland biome.
Tidal zones, Eastern
Pacific Ocean, Pacific Northwest tidal zones, and Puget Sound tidal zones are
all specific ecosystems within the marine biome.
