Answers
1
Different species can share the same habitat, but competition among them is reduced if they
increase their populations
reproduce at different times
eat less
occupy different niches
2
Which of the following statements is NOT true about the oceanic zone
oceanic zone begins low tide mark, extends to end cont shelf
the open ocean has very low levels of nutrients
deep oceanic zone animals r exposed to cold temps n darkness
most photosynthetic activity in ocean occurs in open ocean
3
The climate zone that receives the most direct sun throughout the year is between
90o N and 23.5o N
0o N and 23.5o S
23.5o N and 23.5o S
23.5o S and 66.5o S
4
Earth has three main climate zones because of differences in latitude and
ocean currents
angle of heating
the amount of solar energy received
prevailing winds
5
symbiosis in which both species benefit is called
commensalism
parasitism
mutualism
predation
6
What is one difference between primary and secondary succession?
primary modifies the enviornment, secondary does not
secondary begins on soil, primary begins new exposed surface
primary is slow and secondary is rapid
secondary starts with lichens, primary starts with trees
7
The chemistry of aquatic ecosystems is determined by the
amount of salts, nutrients and oxygen dissolved in the water
amount of rainfall the water recieves
biotic and abiotic factors in the water
the number of organisms present in the water
8
Ponds and lakes are
wetlands
estuaries
standing-water ecosystems
flowing water ecosystems
9
What two biomes have the least amount of precipitation
boreal forest and temperate woodland and shrubland
tropical savanna and tropical dry forest
tropical rain forest and temperate grassland
tundra and desert
10
primary succession can begin after
a severe storm
farmland is abandonded
a forest fire
a lava flow
11
An example of a place with a microclimate is
an orchard growing in a rain forest
a mountain range capped in ice
coniferous trees in a temperate woodland
a forested park in a desert city
12
The loss of heat to space is slowed by
solar energy
the biosphere
atmospheric gases
radiation entering the atmosphere
13
which biome is characterized by very low temperatures, little precipitation, and permafrost
tundra
tropical dry forest
desert
temperate forest
14
The average year-after-year conditions of temperature and precipitation in a particular region
latitude
climate
weather
ecosystem
15
symbiotic relationship between flower and the insect that feeds on its nectar is an example of
mutualism- the flower provides food flower is pollinated
commensalism- flower isnt harmed but does not benefit
parasitism- the insect lives off the nectar
predation because the insect feeds on the flower
16
The series of predictable changes that occur in a community over time is called
climate change
population growth
ecological succession
climax community
17
Which is a biotic factor that affects the size of a population in a specific ecosystem?
concentration of oxygen in the ecosystem
average temperature of the ecosystem
type of soil in the ecosystem
number and kinds of predators in the ecosystem
18
The tendency for warm air to rise and cool air to sink results in
global wind patterns
ocean upwelling
climate zones
unequal heat distribution
19
An important role of pioneer species in primary succession is..
to move in covered wagons from Kansas to the west
break rocks to form soil and add organic nutrients to soil
to pine an ear
to help bullfrogs find their niche
20
Which is NOT an adaptation that organisms have for living in flowing water?
streamlined bodies
hooks
suckers
tentacles
21
the photic zone
is where chemosynthetic bacteria are producers
is deep, cold, and permanently dark
extends to a depth of about 200 meters
extends to the bottom of the open ocean
22
Several species of warblers can live in the same spruce tree ONLY because they
eat different foods within the tree
occupy different niches within the tree
have different habitats within the tree
can find different temperatures within the tree
23
an interaction in which one organism captures and eats another is called
predation
symbiosis
mutualism
competition
24
Single celled algae that grow in lakes and ponds are called
rhodedendrons
biotickton
boreal forest
phytoplankton

all of these
27
Climate is a global factor that produces
Earth's unique ocean and atmosphere
the shape and elevation of land masses

0 degrees
90 degrees N
23.5 degrees N
66.5 degrees N
29
