In this assignment, you will be creating a
trophic pyramid, also known as an “ecological pyramid,” for a
specific ecosystem. 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 go to
httpss://lc.gcumedia.com/bio220/biome-explorer/v2.1/index.html to retrieve the
trophic pyramid worksheet. When completing the worksheet follow the guidelines
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 and Ecosystems.”
Utilize credible sources to select and research your chosen ecosystem,
including the textbook and the Internet (specifically, you may find the
following pages helpful for marine ecosystems:
httpss://www.eoearth.org/view/article/154467 and for terrestrial ecosystems: httpss://www.eoearth.org/view/article/156487).
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.
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).
Refer to the text for further information and an explanation of trophic
Using your completed trophic pyramid,
insert a section break at the bottom of the worksheet and answer the following
questions in 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.
What species did you select for the apex predator? Explain the
importance the apex predator’s impact on the other species in your tropic
How did the amount of energy gained compare to the amount of energy lost
as heat at the 2nd–4th trophic levels?
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?
Can efforts to save a species from extinction be successful if the focus
of preservation is only on that species? Explain your answer
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
