This document provides information about different biomes including temperate deciduous forests, tropical rainforests, deserts, tundra, grasslands, and freshwater and saltwater biomes. It describes the key characteristics of each biome such as average precipitation, temperature, dominant plant and animal species, and adaptations organisms have for surviving in each environment. Examples are given of plant and animal species found in each biome.

1. 2.05 Biomes!!!
You need to know the Tundra,
Desert, Temperate Deciduous
Forest, Rain Forest, Grasslands
and the Water Biomes

3. Forests:
1. Places where there is enough rain and
right temperatures to support trees
2. Types of forest depend on rainfall and
temperature:
a. Temperate Deciduous Forest
b. Coniferous Forest (Taiga)
c. Tropical Rain Forest

5. - Biomes

6. Temperate (Deciduous) Forest of North America

7. 1. Average Precipitation: 75 cm to 150 cm
yearly
2 usually 4 seasons a year with
temperature differences (TEMPERATE)

8. Deciduous Forest Plants
Deciduous = losing leaves,
becoming dormant plants in the
Most
Oak trees, pine trees, dogwood
deciduous forest lose
their leaves in the fall.
Some drop seeds that
start a new life in the
spring and others
remain dormant
underground until the
new year begins.

9. Grey Squirrel
Goshawk
Raccoon
Deciduous Forest Animals
Animals within this biome
must adapt to cool winters
and do so by hibernating,
migrating, or by staying
active.
Spring Peeper
White-tailed deer

12. 1. Lots of Precipitation: 200 cm to 500 cm each
year
2. Temperatures are warm and stable – very
HUMID!
3. Lots of species of plants and animals
a. Plants: Vines, orchids, moss, ferns, trees
b. Animals: 150 different types of
butterflies, snakes, Lizards, salamanders,
monkeys, Bats, Jaguars, Birds

13. Tropical Rainforest Plants
Rainforest Plants have
adaptations that help them to
catch water. They grow fast
and usually have a large root
system to help the plant trap
nutrients from the soil.
They grow fast, have large
leaves to catch sunlight.

14. Tropical Rainforest
Animals
Orangutan
Located near the equator, animals
are usually colorful which can
mean ‘DANGER’. They hold over
half of the world’s known species!

17. Deserts of America

18. 1. Dry – not a lot of rain – less than 25 cm per year
a. Because there is little water, plants are spread widely
apart and the ground is mostly bare
1. Hot during day, cold during nights
2. Poor soil
4. Few large animals are found because there is
not enough food or water to support them.

19. Desert Plants Adaptations
Plants in the desert have thorny
spines that help defend them,
fleshy stems to store water, and
have a large root base to collect
water successfully.

20. Cactus Wren
Desert Animals
Desert Animals have special
adaptations to deal with the lack
of rainfall for this biome. Many
are NOCTURNAL and they only
come out at night to hunt and eat
when it’s cooler. Some animals
don’t even drink water! They get
their water from seeds or plants.
Sidewinder
Thorny
Lappet-faced Vulture
Desert Scorpion

22. - Biomes

23. 1. Is located near the polar regions
2. Cold, dry, treeless region and is covered
with ice most of the year
3. Winters are 6 to 9 months long
4. Precipitation ~ less then 25cm a year
a. Just like a desert – a COLD desert
4. Ground covered with a layer of
permanently frozen soil = permafrost

24. 6. Plants:
– lichens (reindeer moss) , True mosses,
Grasses, Small shrubs
7. Animals - in the summer
– Mosquitoes
– Birds (Geese, ducks, snowy owls)
– Mice, voles, lemmings, artic hares, caribou,
musk oxen

25. 8. Adaptations:
a. Thick fur, blubber, camafloauge
b. Mosquitos with anti-freeze in body
c. Most plants have dense shallow roots to
conserve water

27. - Biomes

28. 1. There are grasslands on almost every
continent
2. Precipitation: 25 cm to 75 cm yearly
a. They have a dry season with little to no rain
b. This prevents larger plant from growing here
3. Main plant is grass

29. 4. Plants: Grass such as:
– Wheat, Oats, Barley, Corn
– Grasses have extensive root systems that can
absorb water when it rains and can withstand
drought during long dry spells
5. Animals
– Kangaroos, Wildebeests, Zebras, Prairie Dogs
– They eat the stems, leaves, and seeds of
grass plants

30. Fresh water biomes
1. Not salty water
2. Very important resources - drinking water
3. Examples: lakes, rivers, stream,
wetlands
4. Lots of animals and plants: sea weed,
lilies, turtles, fish, birds, amphibians

31. Salt water Biomes
1. Very high salt content
2. Very important resource – food, water
3. Examples – oceans, seas, bays,
estuaries
4. Lots of animals/plants: sea weed, algae,
kelp, sharks, fish, turtles, snakes,
dolphins, mammals, birds
