Ecology
•Habitat
•Biomes
•Food Chains
•Life…even Microscopic Life!
Habitat
• the type of
environment in
which an
organism lives;
where an
organism is
commonly found.
• Four Important
Components:
food, shelter,
water, space
Riparian Zone Habitat
• areas that surround water
bodies in the watershed
and are composed of
moist to saturated soils,
water-loving plant species
"Riparian Retreat"
3rd Grade Classroom #4
Prairie
Habitat
• Living birdfeeder
• Deep roots, hold soil
>reduce soil
pollution/run-off >
improve water quality >
retain moisture in
ground
• Provides habitat & food
Habitat Quality
• The overall
quality of habitat
has been
degraded due to
human habitat
expansion=
habitat
degradation.
Degradation = Invasives
Biome
• Classified by
• predominant
vegetation
• similar climate
• adaptations of
organisms
• They have moved
& changed many
times in Earth’s
history

Polar Biome (Tundra)
World's youngest biome! Formed about
10,000 years ago. Treeless, very cold,
ground permanently frozen (why trees
can't grow there), low growing plants
(mosses, lichen), summer it thaws for a bit
forms large bogs, swamps, LOTS insects
reproduce = happy migratory birds ;
major carbon sink
Tally Time!
Desert Biome
• Hot during the day, cool at night,
receive less than 50 cm rainfall / year.
DRY!
• Plants - hold in a lot of water for a
long time.
EX: fishhook cactus, sugauro cactus
• Animals - most nocturnal
EX: thorny devil, bilby, camel,
jackrabbit, rattlesnake, kangaroo rat
Coe Lake – Temperate Deciduous
• 4 distinct seasons (spring,
summer, autumn, winter)
• Plants – leaves change color in
autumn & are dropped in winter.
EX: oak, maple, beech
sycamore, sassafras, red bud,
black cherry, locust
• Animals – many hibernate
during winter EX: american
toad, box turtle, ground squirrelchipmunk, arboreal squirrelgray squirrel, opossum, black
bear, raccoon, cedar waxwing,
cardinal, brown thrasher
Trees Trees Trees
More Plants
• Serviceberry
• Tupelo Tree
Animals at Coe Lake
Food Chain
• Path of food consumption
(transfer of E) from sun, to plants
to animals and more animals.
• Producer
• Primary Consumer
• Secondary Consumer
• Tertiary Consumer
• Herbivores, carnivroes,
omnivores,decomposers
Energy Moves Through Food
Chains
The circle above
represents the
producer. All of the
stored energy in the
body of the
producer organism
is eaten by the
primary consumer.
The circle above
represents the
primary
consumer. A
small portion of
the producer's
original energy is
stored in the
primary
consumer.
The circle above
represents the secondary
consumer. Only a very
small fraction (shown in
green) of the producer's
original energy is stored
by the secondary
consumer. This energy is
taken into the body of the
tertiary consumer.
• As the energy is passed along the food chain
much of it is either used or lost. Therefore there
is a limit to the number of organisms in a food
chain. The top carnivore is usually the third or
fourth consumer.
•
The pyramid below is a way of showing how the numbers of organisms decrease
along the food chain, finishing with the top carnivore at the apex.
A = plankton, B = shrimp, C = fish, D = seagull
Microscopic Life is Really
Important in Food Chains
• Life (algae,
protists,bacteria) you
can not see
• Need microscope to
see
• EX: Daphnia,
Copepods,
Paramecium,
Euglena, Diatoms,
bacteria
Parts of A Microscope
What You Need to Know..
• Define habitat.
• What ecological function/role do riparian zones and
prairies play in ecosystems?
• What is habitat degradation? Thoroughly explain
outcome.
• Biomagnification.
• What are the 3 biomes in "Tally Time" and explain each.
• Identify the components of a freshwater pond/lake
biome. (like Coe Lake )…and plant/animal life there.
• Food Chains.
• Microscopic Life and The Microscope.
