Transcript of Ecology Sec. 1.4 notes

Pop Quiz
Tundra & Taiga
Desert & Grassland
Temperate & Tropical Forest
Water covers most of the Earth's surface
Regions of Earth are classified into biomes
Biome: a region of
Earth
that has a particular type of
climate
and certain types of
plants
.
tundra, taiga, desert, grassland, temperate forest, tropical forest.
Tundra
: long
winters
, less than
25 cm
of precipitation each year

Permafrost:
a deep layer of permanently
frozen soil
just below the surface soil.
4.
Plants=mosses, grasses, woody shrubs, lichen

animals= rodents, caribou, musk oxen, grizzly bears, white fox, snowy owls


Taiga:
30 t
o
60 cm
precipitation, ground is cold but
not frozen.
Coniferous trees have
needlelike
leaves that produce
food
all year long. Animals : deer,
elk,
snowshoe hares,
beaver,
lynx, owls, bears, and wolves
5. Taiga has tall trees & bushes; tundra has only low-growing plants.
6. Permafrost prevents the growth of the large, deep root systems of large plants in the tundra.
Sec. 1.4 - Biomes contain many ecosystems
Desert
:
dry
soil, less than
25 cm
of precipitation
Plants
: cactus, creosote bushes, shrubs
Animals
: lizards, ground squirrels, rodents, snakes, owls, and foxes

Grasslands
:
50
to
90
cm of precipitation year.

Plants
: grasses, shrubs, wild flowers
Animals
: rodents, bison, horses, gazelle, zebra, wolves, tigers, and lions

7.
Desert has bare soil with rocks and cacti; grassland soil is covered with grasses & wildflowers.
8.
Grasslands receives more rain and have richer soil
than deserts do.
Temperate forest
:
Four
seasons,
75
to
150
cm of precipitation each year.D
eciduous trees:
l
eaves
drop as w
inter
approaches & grow new leaves in s
pring.
Pl
ants:
large variety of trees and vegetation
Ani
mals: r
odents, chipmunks, squirrels, raccoon, deer, wolves, bobcats, foxes
Tropical forest:

200

to 450

cm
of precipitation. Warm temperatures. Large variety of plants and animals

9.Near
t
he equator, and spreading north & south
10.
water

11.
estuary

12.
Marine biomes, coastal, open ocean, deep ocean
Learning Goal: Describe how energy flows through an ecosystem
1. The organisms in a certain grassland ecosystem include grasses, insects, meadowlarks, mice, and owls. Draw a diagram that shows how these organisms depend on one another for food. Label each organism(s) it feeds on.
Climate
is an important factor in land biomes.Climate describes the long-term
weather
patterns of a region, such as average yearly
rainfall
&
temperature
ranges Climate also affects
soil type.
