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?

What factors do you think had the most effect on your footprint? What can you do to change your footprint? (Note: For those students using a Screen Reader refer to the Directions for Screen Reader Users.)

BIO 220 Grand Canyon Week 2 Discussion 1

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?

BIO 220 Grand Canyon Week 3 Discussion 1

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.

BIO 220 Grand Canyon Week 3 Discussion 2

BIO 220 Grand Canyon Week 7 Discussion 2

Obtain a water quality 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? Predict how the application of the technique(s) would affect your daily life?

BIO 220 Grand Canyon Week 2 Assignment 1

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:

1. 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:

1. 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.
