What’s in an ecosystem?
•We explored an area of
land around our school
and determined the
land’s physical features
and the types of
organisms that live
there.
•We took about 20
pictures of our area:
wide shots and detailed
shots.

Recorded Observations
•Pill Bug
•Woodchips
•Ants
•Green leaf
•Twigs
•Unidentified white bug
Very coarse soil
filled with
woodchips
Dark, fertile soil
Pill Bug
•The pill bug that was in
our sample of soil was
3/4”, oval dark brown,
with 7 legs and antennas.
•The only crustacean that
can spend its entire life on
land. They’re known for
their ability to roll into a
ball, can live up to two
years and are most active
at night.
ANT
•Ants range in size from
0.75 to 52 millimeters.
Their colors vary; most
are red or black, green is
less common. More
than 12,000 species are
currently known with
the greatest diversity in
the tropics.
•They’re able to exploit a wide
range of food resources either
as direct or indirect herbivores,
predators and scavengers. Most
species are
omnivorous generalists but a
few are specialist feeders.
•It was 2 of them but they
weren’t interacting with each
other.
Michigan Soils
• Mostly the soils in
Michigan are all
different types of sand.
One of the most
popular types is
Kalkaska: Black sand
surface layer, brown
sand subsurface layer,
dark reddish and yellow
brown sand
throughout.
• Our soil sample
however was not made
of so many diverse
levels. We had dark
brown coarse coil and
smooth light brown soil
on top.
