2. Work on #2 Define Ecosystem:
2. Define Ecosystem.(continue this on your google doc that you already shared with me)
a. As
you research your biome, select a specific Ecosystem on Earth that represents
your biome. Since you are working at
biome tables, each student at the table must select a DIFFERENT sample
ecosystem. My specific ecosystem is:
_____________.
i. Describe
where on Earth your specific ecosystem is located. Be specific…country, latitude, proximity to
major cities/oceans, etc.
ii. Read
section 6.1-6.3 in your textbook about current challenges that ecosystems on
Earth are facing. Then, research which of these current challenges are impacting your
chosen ecosystem. Write a cohesive
paragraph that includes at least 2 challenges/threats. Be sure to describe the challenges/threats in
detail and describe how they are specifically impacting your ecosystem. You can use this resource as well (http://www.nrdc.org/issues/) to research
other issues that are not listed in your text book.
iii. As
you research these threats, identify endangered/threatened organisms for your
ecosystem. Choose one of these organisms
to focus on for the remainder of your research.
Define niche. What is your endangered/threatened species’
niche in your ecosystem? Be sure to
include ALL of the important roles your organism plays in its ecosystem. My specific organism is:________________.
b. Define
food web.
i. Draw
a food web for your endangered/threatened organism that includes at least 7
organisms
ii. Label
each member of your food web as a primary producer, herbivore, carnivore,
scavenger, or decomposer.
c. Define
trophic pyramid.
d. Define
the 10% Rule
i. Create
a trophic pyramid for a simple food chain in your ecosystem that includes your
endangered organism. Include at least 4
levels in your trophic pyramid and use labels to describe how energy flow from
one level to the next changes.
