Answers

1
Which of the following statements is NOT true about the open ocean?
deep ocean is frigid temps and total darkness
most of earth's photosynthetic activity occurs in open ocean
begins at low tide and extends to end of continental shelf
The open ocean has very low levels of nutrients.
2
Temperatures on Earth remain within a suitable range for life as we know it because of the
greenhouse effect.
unequal heating of Earth’s surface.
loss of heat to space.
radiation of sunlight back into the atmosphere.
3
Why does Earth have three main climate zones?
landmasses physically interfere with global heat
Warm air rises at equator and cold air sinks over the poles
Earth rotates and affects the major ocean currents
differences in latitude
4
The unequal heating of Earth’s surface
drives wind and ocean currents.
causes winds that transport heat throughout the biosphere.
all of the above
has important effects on Earth’s climate regions.
5
which animal would you find in a temperate forest?
iguana
whitetail deer
polar bear
moose
6
Which two biomes have the least amount of precipitation?
tundra and desert

mutualism
parasitism
predation
commensalism
8
Each of the following is an abiotic factor in the environment EXCEPT
plant life.
temperature
soil type.
rainfall.
9
Earth has three main climate zones because of the differences in latitude and, thus,
amount of precipitation received.
angle of heating.
prevailing winds.
ocean currents.
10
Which factor(s) can influence continual change in an ecosystem?
introduction of nonnative species

12
symbiotic relationship between a flower and the insect that feeds on its nectar is an example
predation
parasitism
mutualism
commensalism
13
All of the following factors contribute to Earth’s climate EXCEPT

an orchid growing in a rain forest.
15
Which of the following occurs during the ecological succession of an ecosystem?
organisms modify their environment a little at a time
Parts of communities split off
An ecosystem reaches a final, unchanging stage.
Changes caused by organisms outside the ecosystem
16
An interaction in which one organism captures and feeds on another organism is called
mutualism
predation
competition
sybiosis
17
Which biome is characterized by very low temperatures, little precipitation, and permafrost?
temperate forest
desert
tundra
tropical dry forest
18
The chemistry of aquatic ecosystems is determined by the
amount of salts,nutrients, and oxygen dissolved in the water
amount of rainfall the water receives.
the number of other organisms present in the water.
biotic and abiotic factors in the water.
19
Several species of warblers can live in the same spruce tree ONLY because they
occupy different niches within the tree.
have different habitats within the tree.
can find different temperatures within the tree.

20
Primary succession can begin after
a severe storm.
farm land is abandoned.
a forest fire.
a lava flow.
21
No two species can occupy the same niche in the same habitat at the same time
unless the species require different abiotic factors.
unless the species require different biotic factors.
because of the interactions that shape the ecosystem.
because of the competitive exclusion principle.

estuaries
23
The series of predictable changes that occurs in a community over time is called
climate change.
climax community.
ecological succession.
population growth.
24
Different species can share the same habitat, but competition among them is reduced if they
occupy different niches.
eat less.
increase their populations.
