Answers

1
humans impact grasslands by
grazing domestic herds
all of these answers
drilling for water and oil
planting crops
2
fish adapted to dark, cool waters in a lake are found in which zone
benthic zone
limnetic zone
profundal zone
littoral zone
3
the taiga is...
dry, rocky biome in S. America
a cold, treeless desert
found mostly in Africa
forest dominated by conifers such as spruce, fir, pines
4
adaptations of animals in the desert include
large, bulky size to retain body heat
thin skin to absorb water
searching for water at midday
searching for food at night
5
types of organisms in ponds & lakes depend on
temperature of water
all of these answers
presence of nutrients
amount of sunlight available
6
the tundra...
too cold to support insect life
encounters no environmental damages
is found only in South America
has permafrost which topsoil may only thaw a few weeks
7
Grasslands (such as N. American Prairie)
are threatened by erosion due to plowing & overgrazing
support rich layer of grasses b/c receive 100in.+ of rain
support no animal life after disappearance of buffalo
are not suitable for growing soybeans
8
in lakes, the nutrient-rich water near the shore is part of the
profundal zone
littoral zone
benthic zone
limnetic zone
9
estuaries receive water from
creeks & geysers
rivers & oceans
streams & springs
lakes & ponds
10
which biome name does not belong with the others
tropical savanna
boreal forest
taiga
northern coniferous forest
11
which of these is NOT an env. function of wetlands
trapping carbon
increasing runoff
controlling floods
removing pollutants from water

bacteria
13
most marine organisms are found in
open ocean
fisheries
shallow, coastal waters
deep ocean waters
14
biomes...
are described by vegetation and climate
exist in limited regions of the world
are only the major types of forests
contain 2 ecosystems, thus bi-ome
15

tundra
Beaver Creek
temperate deciduous forest
tropical scrub forest
16
water storing plants are most likely found in which ecosystem?
high altitudes
cold ecosystems
aquatic habitats
deserts

which are evergreen plants in the taiga?
algae & seaweed
conifers (pine, cedar, fir, spruce trees)
maples & oaks
bacteria
18
which is NOT a threat to coral reef ecosystems?
eroded soil from deforestation & poor land management
predation by sharks
chemical pollution & oil spills
warming waters due to global climate change
19
the 2 types of freshwater wetlands are
rivers & streams
lakes & ponds
marshes & swamps
littoral zones & benthic zones
20
adaptations by animals in the tundra include...
rodents burrow underground
geese & caribou migrate
arctic foxes use seasonal camouflage
all of these answers are true
21
2 most important factors to determine climate are
temperature & ocean currents
moon & stars
precipitation & light
temperature & precipitation
22
coral reefs are a result of
secretion of limestone (calcium carbonate) by coral
minerals washed from land
volcanic activity
accumulations of skeletons of tiny fishes
23
threats to tropical rain forests include
decrease in temp. at equator
thinning of the soil
deforestation & trade of plants & animals
decrease in rainfall at equator
24
estuaries exhibit
variable temp. & constant salinity
constant temp. & variable salinity
constant temp. & salinity
variable temp. & salinity
25
adaptations by animals in the desert include
hibernation in winter
thin skin to absorb water
include caribou, moose, snowshoe hare
nocturnal
