Complete the “Scientific 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

Column 1: Scientific Method Steps Column 2: Examples of Tasks

 
___ Observe
___ Ask a question
___ Create a hypothesis
___ Conduct an experiment
___ Collect data
___ Interpret results
___ Report results

 
  1. 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.
  2. 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.
  3. c) A scientist wonders if the waste water emitted from an industrial plant is accelerating the growth of algae in a pond.
  4. d) After five days, the scientist measures the amount of algae present in each dish.
  5. e) The scientist submits his findings to a scientific journal.
  6. 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.
  7. g) A scientist observes that a pond adjacent to an industrial plant has heavier algae growth than ponds farther away.

BIO 220 Grand Canyon Week 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:

  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.

Course Final Report Task 1

Review “Course Final Report: Overall Project Review.” 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. For Task 1, identify one environmental issue that has impacted you or someone you know. The issue that you pick will be the topic for your course final report. For help in selecting topics, refer to “Suggestions for Environmental Topics.” To successfully complete task 1, do the following:

  1. Briefly describe the selected environmental issue.
  2. State your initial position on the issue in one to two paragraphs.
  3. Find three articles that support your position.
  4. List all the references at the end of the report according to the guidelines found in the GCU Style Guide, located in the Student Success Center.
