Biome Project
Day 1
•Biotic and abotic
factors
•Climatograms
Bio- means life
A- means without
Biotic factors are
those things that
have life.
Ex. Trees, squirrels,
bears, humans
Abiotic factors are
those things that are
without life
• Ex. Rocks, soil, water,
wind, climate
Ecology is the study
of the relationships
between the biotic
and abiotic factors.
Climatograms
• Are graphs that show two
important abiotic climatic
factors – temperature and
precipitation.
–Temperature is plotted as a
line graph.
–Precipitation is plotted as a
bar graph.
Day 2
•Food chains/ food
webs
Food
Chain
shark
fish
paramecium
algae
•The arrows point in
the direction of energy
flow
•Food web: a group of
connected food chains
Trophic level:
the place of an
organism on a food
chain
Tertiary
consumer
Secondary
consumer
Primary consumer
producer
Day 3
•Energy pyramids
bass
minnows
paramecium
algae
Only 10-20% of the
energy moves to the
next level on the
pyramid.
Why is it rare to have
animals that eat the
tertiary consumer?
Day 4
•niches
Habitat
the place where an
organism lives
Ex. A tadpole lives in a
pond
Niche:
all strategies and
adaptations a species
uses in its environment
to meet its needs at a
given time
Niche
-how an organism
meets its needs for
food and shelter
-how and where it
survives
-where it reproduces
Niche includes that
organisms interactions
with biotic and abiotic
parts of the habitat.
No two organisms can
fill the same niche at
the same time in the
same habitat. So, each
organisms niche is
unique.
An organism in a niche
has adaptations that
give it an advantage
over other organisms
that may be competing
for the same niche in
the same environment.
Example: A leopard frog
• lives in & along the shore of
ponds
• is a predator that captures
insects with its sticky tongue
• reproduces by laying jellylike eggs in the shallow
water
Day 5
•Symbiosis
All those organisms
living together in the
wild end up forming
relationships.
(well, not
really like
that)
Lichen is made out
of algae and a
fungus.
The algae gives
food to the fungus.
The fungus
protects the algae.
The relationship
between the algae
and fungus is called
mutualism.
(Think “mutual”)
In mutualism, one
helped
species is _______
while the other is
helped
_________.
(helped, hurt, not affected)
Meet Harvey:
He’s my tapeworm. He
lives in my intestines
and steals my food.
The tapeworm and I
have a relationship
called parasitism.
How is a parasite
different from a
predator?
In a parasitism, one
helped
species is _______
while the other is
hurt
_________.
(helped, hurt, not affected)
Certain fish live just
beneath sharks to
catch food scraps.
The shark and fish
have a relationship
called
commensalism.
In commensalism,
one species is
helped
_______while the
other is
Not
affected
_________.
(helped, hurt, not affected)
Parasitism,
commensalism, and
mutualism are all
forms of symbiosis.
Symbiosis:
When organisms
from
DIF FERENT
species LIVE in a
relationship
