Chaparral plants usually survive fires because

they can resprout from small amounts of living plant tissue.

Which of the following is an adaptation of coniferous trees in the taiga?

Their needles hold snow, to act as an insulating layer.

are often described by their plants

Which of the following best describes a tropical rain forest?

lots of species with specialized survival techniques

Tropical rain forests are threatened by

deforestation and the trade of rain forest plants & animals.

has a permanently frozen layer of soil beneath the topsoil.

a forest biome dominated by trees with cones like pine trees

As you travel from the North Pole toward the equator, you would expect to see

tundra, then grasslands, then tropical rain forests.

often formed on the dry side of mountain ranges.

If you visited a savanna, you would likely see

herds of grazing rhinos, gazelles, and giraffes.

The deforestation of the rain forests may cause climate changes which, in turn, may affect

the ability of the rain forest to ever regrow again

The main factor/s that determines what type of plants grow in a biome is

both temperature and precipitation

Answers

1
Adaptations of desert animals that help them survive in the hot, dry desert often include
searching for water at midday.
large, bulky size to retain body heat on cold nights.
thin skin that readily absorbs water.
searching for food at night.
2
Chaparral plants usually survive fires because
water is stored in their small, leathery leaves.
they can resprout from small amounts of living plant tissue.
of deep root systems that keep them moist during a fire.
they contain oils that act as natural fire extinguishers.
3
Which of the following is an adaptation of coniferous trees in the taiga?
They have a shallow root system, due to the acidic soil.
Their needles hold snow, to act as an insulating layer.
They are green to blend in.
Their leaves hold water, due to their shape & waxy coating.
4
Biomes
contain two ecosystems
are often described by their plants
can have very different ecosystems as part of them
exist in few regions of the world.
5
Which of the following best describes a tropical rain forest?
lots of species with specialized survival techniques
very few species of trees, due to poor soil quality
rich soil that supports lots of plants on the forest floor
plants and animals that are very similar
6
Tropical rain forests are threatened by
a decrease in rainfall at the equator.
a decrease in the average temperature at the equator.
a thinning of the soil.
deforestation and the trade of rain forest plants & animals.
7
The tundra
All of these
is resistant to environmental damage because its frozen.
has a permanently frozen layer of soil beneath the topsoil.
is too cold to support insect life.
8
Which biome has a Mediterranean-style climate with warm, dry summers and mild, wet winters?
tundra
tallgrass prairie
chaparral
savanna
9
a temperate rain forest would most likely be found
the Pacific Northwest
on the lee side of a mountain
somewhere near the Arctic Circle
somewhere near the equator
10
Taiga is
a forest biome dominated by trees with cones like pine trees
found mostly in Africa.
a cold, treeless, desert-like biome found near the Poles.
a dry, rocky biome found in the north part of South America.
11
As you travel from the North Pole toward the equator, you would expect to see
temp. deciduous forests, taiga, then tropical rain forests

taiga, then desert, then tundra.
tundra, then grasslands, then tropical rain forests.
12
Deserts are
covered with sand and contain no plant life.
never located in cooler climates.
found only in Africa
often formed on the dry side of mountain ranges.
13
Animals that live in the desert
include camels, moose, and various reptiles.
usually have thin skin to absorb water.
hibernate in winter.
are usually nocturnal.
14
The distance north or south of the equator, as measured in degrees, is called
longitude.
altitude.
magnitude.
latitude.
15
If you visited a savanna, you would likely see
a dry sandy ecosystem
herds of grazing rhinos, gazelles, and giraffes.
a coastal ecosystem.
prairie dogs and buffalo
16
The deforestation of the rain forests may cause climate changes which, in turn, may affect
smog.
the ability of the rain forest to ever regrow again
acid precipitation.
the richness of the soil where deforestation took place
17
Which of the following would you expect to see in the emergent layer of a tropical rain forest
grasses, insects, and small succulents
lichens, mosses, and dwarf woody plants
epiphytes, small burrowing mammals, and burrowing toads
eagles, bats, and snakes
18
The main factor/s that determines what type of plants grow in a biome is
altitude.
precipitation.
temperature.
both temperature and precipitation
19
Adaptations demonstrated by plants in tropical rain forests include
above ground roots that increase stability.
herbs with large flat leaves located in the understory.
orchids and vines that use tall tree trunks for support.
all of these
