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.
