1. Describe the difference between the Deciduous Forest and the Coniferous Forest Biomes.
2. How are the TUNDRA and DESERT similar? How are they different?
1. Put ANSWERS INTO I-RESPOND…. (I will call you up to do so.) Not everyone can use an
i-respond at once.
2. While we are waiting, you should be working on the AQUATIC BIOMES WORKSHEET if needed. It needs to be handed in when you are finished.
3. BIOME PASSPORT FILL IN– We will work as a class to fill in any gaps in your passport books.
Please take careful notes!! You will use the Biome books for your
upcoming Biome project!

Temperature: Summer: 28 Deg. C (82 F)
Winter: 6 Deg. C (43 F)
Rainfall: 75-125 cm (29.5-49in)
Soil: Fertile (Allows many different types of trees to grow)
Common Plants(Flora): Trees-oak, beech, maple, elm, willow
Flowering herbs
Plant Adaptations: Leaves fall off the trees in order to conserve water
Common Herbivores: ◦ Possums, rabbits,
squirrels, raccoons, deer
◦ Common Carnivores: Bears, snakes,
woodpeckers
Animal Adaptations: ◦ Some animals
hibernate in the winter
◦ Animals gather food to store to make it through the winter
◦ Many grow thicker
coats to keep warm in winter and shed in summer
4 Seasons (summer, winter, spring, fall)
Found in the eastern half of North America, middle of Europe, Asia, New Zealand and Australia
Losing land due to farms and humans building (some areas protected)
Temperature: Summer:14
Deg C(57 F) Winter: -10 Deg. C (14 F)
Rainfall: 35-75 cm (14-29.5 in)
Soil: thin, nutrient poor, and
acidic
Common Plants (Flora):
Conifer trees (have seeds, pinecones) Pine, Fir, Spruce
Plant Adaptations: ◦ Conifer trees have a waxy
coating to prevent them from drying out, and protects them from cold winters
◦ Trees stay green all year round– called evergreen trees
Common Animals: ◦ Woodpeckers, hawks,
moose, bear, weasel, lynx, fox, deer, chipmunks, bats
◦ Animal Adaptations: Hibernation
Migration
Storage
Body and Color Adaptation (thicker coats in winter, different colors)
The Coniferous Forest has cold, long, snowy winters, and warm, humid summers; well-defined seasons, at least four to six frost-free months.
Temperature: Daytime: 34 Deg C (93 F) Nighttime: 20 Deg C (68 F) (Doesn’t have distinguished seasons)
Rainfall: up to 400cm per year (157.5 in)
Soil: Nutrient poor, acidic, topsoil is only 2 inches Where rainforests are located: -Central America -Africa -Indo-Malaysia India -Southeast Asia, - New Guinea and Australia.
Common Plants (Flora):
Highly diverse plant life, has more kinds of trees than any other area in the world, Only covers 6% of the Earth’s surface, but provides 20% of our oxygen.
Plant Adaptations: ◦ plants shed water off
their leaves quickly so the branches don't get weighed down and break
To absorb as much sunlight as possible, leaves are very large
Common animals:
◦ Jaguar, many tropical
birds, small mammals, Insects make up the largest single group of animals
Animal Adaptations:
Savannas (Tropical Grasslands)
Contain the greatest number of grazing animals on Earth.
Location: Found in the tropics…near equator
Amount of precipitation supports tall grasses but only occasional trees.
The word savanna stems from an Amerind term for plains

Tropical Savanna
Abiotic Factors Temperature: Dry Season- 34 Deg C (93 Degrees)

Threats to the Tundra
One of the most fragile biomes on the planet
The tundra is
slow to
recover from
damage.
Oil drilling
is
proposed
in Alaska
and other
areas!
Tufted Saxifrage

been a concern.

Will vary based
on where in
the river they
are…at the
headwaters,
organisms
need to hang
on!

Threats to Rivers
Industry uses
water to
dispose of
waste products
Runoff from
homes and
other places
causes
changes in
acidity,
pollution, etc.
Dams alter the
flow of the
water

Plant and Animal Adaptations of
Estuaries
Very productive
biome because
it receives lots
of light and
nutrients
Often used as
nursery for
young www.lookoutnow.com & www.visualparadox.com
Manatee and
goose
Threats to Estuaries
Many ports are found
on estuaries—
pollution
Human population

Breeding area for many fish
http://mbgnet.mobot.org/salt/coral/
Animal adaptations of
the Coral Reef
Threats to the Coral Reefs
Temperature is important,
too hot or too cold and
the animals can’t live
there to create limestone
Human intrusion (scuba diving)
is damaging if you
touch/step on the reef
Pollution is also a concern.
www.calacademy.org
Ocean Abiotic factors
Open ocean is one of
the least productive
areas on earth, too
little sunlight to
support plant
growth
Covers nearly
¾ of the
Earth’s
surface.

mes_aquatic.htm
Ocean Animal Adaptations
Zooplankton—
sea’s smallest
herbivores
Deep ocean animals
feed on detritus—
floating debris in the
water column.

Hammerhead
Lion fish
Threats to
the Oceans
While the
oceans are
vast, they
are
becoming
more
polluted
Overfishing
and some
fishing
methods are
destroying
fishing
grounds. http://www.worldbiomes.com/biomes_aquatic.htm
Polar Ecosystems
Can be
considered
marine
ecosystems
since the base
of food chain is
phytoplankton
www.defenders.org

Arctic vs. Antarctic
Arctic
Relatively
shallow, lots of
nutrients for
large variety of
animals in food

Antarctic
Penguins live
here—only continent
not used by humans
(exc. Research)
Threats to the Polar Ecosystems
Reserves of minerals
draw humans to
these fragile
ecosystems.
The main threat to
wildlife has been
the increase in
tourism—garbage

Oceans
Photic Zone– Portion of marine biome that is shallow enough to penetrate sunlight
(coastlines-shore, beaches, mudflats)
Aphotic Zone– Deeper Waters that do not receive sunlight. (Deep, least explored oceans)
Phos- Light (Greek)
A- Without (Greek)
Largest amounts of biomass (living materials) though often very small
Whales, seals, sea otters, sea cows
Kelp, algea, sea grass
Bay, sound, fjord, salt marshes, wetlands
Freshwater mixes with salt water (some land)
Brackish Water (more salt than freshwater; but less than marine)
Salinity ranges ◦ Amount of freshwater vs. Saltwater
◦ Tides
◦ Biodiversity
Eelgrass, smooth cordgrass, sea lavender
Shiner Perch, Starry Flounder Orange Striped Jellyfish, Purple Shore Crab, Scallop
Predators– cranes and other birds
Decay of dead organisms is quick, nutrients recycled through food web.
Major abiotic factors: temperature and light
Not enough sunlight penetrates to bottom to support photosynthesis ◦ Few aquatic plants or algea grow
◦ Population density lower
◦ Bacteria break down dead organisms and recycle nutrients
