Answers
1
Different species can share the same habitat, but competition among them is reduced if they
occupy different niches
eat less
reproduce at different times
increase their populations
2
Which is NOT an adaptation that organisms have for living in flowing water?
hooks
suckers
tentacles
streamlined bodies
3
What is one difference between primary and secondary succession?
secondary starts with lichens, primary starts with trees
secondary begins on soil, primary begins new exposed surface
primary modifies the enviornment, secondary does not
primary is slow and secondary is rapid
4
The loss of heat to space is slowed by
radiation entering the atmosphere
the biosphere
atmospheric gases
solar energy
5
Which is a biotic factor that affects the size of a population in a specific ecosystem?
number and kinds of predators in the ecosystem
type of soil in the ecosystem
concentration of oxygen in the ecosystem
average temperature of the ecosystem
6
the unequal heating of Earth's surface
has important effects on Earth's climate regions
all of these
causes winds that transport heat throughout the biosphere
drives wind and ocean currents
7
Climate is a global factor that produces
wide range environmental conditions that shapes communities
Earth's unique ocean and atmosphere
solar energy within the atmosphere
the shape and elevation of land masses
8
The climate zone that receives the most direct sun throughout the year is between
23.5o S and 66.5o S
90o N and 23.5o N
0o N and 23.5o S
23.5o N and 23.5o S
9
Weather is the average
century to century conditions
year to year conditions
day to day conditions
decade to decade conditions
10
Earth has three main climate zones because of differences in latitude and
prevailing winds
the amount of solar energy received
ocean currents
angle of heating
11
An example of a human caused disturbance is
growing lichens
forest-clearing
wildfires
hurricane
12
an interaction in which one organism captures and eats another is called
competition
mutualism
symbiosis
predation
13
symbiotic relationship between flower and the insect that feeds on its nectar is an example of
parasitism- the insect lives off the nectar
mutualism- the flower provides food flower is pollinated
commensalism- flower isnt harmed but does not benefit
predation because the insect feeds on the flower
14
What factor can influence continual change in an ecosystem?
further disturbances
long-term climate change
introduction of nonnative species
all of these
15
Organisms within an ecosystem are ___ factors in that ecosystem
life forms
phytoplankton
biotic
abiotic
16
The tendency for warm air to rise and cool air to sink results in
ocean upwelling
global wind patterns
climate zones
unequal heat distribution
17
Barnacles on a whale is an example of what kind of relationship?
parasitism
predation
commensalism
mutualism
18
The series of predictable changes that occur in a community over time is called
climax community
climate change
ecological succession
population growth
19
North polar zone is between ________ latitude and the north pole
66.5 degrees N
23.5 degrees N
0 degrees
90 degrees N
20
These factors contribute to global climate patterns
trapping of heat by the atmosphere and latitude
transport of of heat by winds and ocean currents
the shape and elevation of landmasses
amount of precipitation
21
What organisms are found in an climax community of a forest
trees and shrubs
lichens and moss
volcanoes and soil
weeds and grasses
22
An important role of pioneer species in primary succession is..
to help bullfrogs find their niche
to pine an ear
to move in covered wagons from Kansas to the west
break rocks to form soil and add organic nutrients to soil
23
Generally cool air over the poles ....
rises
sinks
flow parallel to the earth's surface
absorbs heat from the equator
24
What two biomes have the least amount of precipitation
tundra and desert
tropical rain forest and temperate grassland
boreal forest and temperate woodland and shrubland
tropical savanna and tropical dry forest
25
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
can find different temperatures within the tree
have different habitats within the tree
26
Atmospheric gases that trap heat inside Earth's atmosphere area called _____ gases
heat gases
hot gases
greenhouse
atmospheric
27
the energy of incoming _____ drives Earth's weather and helps to determine climate
comic rays
greenhouse effect
sunlight
what is energy??
28
The average year-after-year conditions of temperature and precipitation in a particular region
ecosystem
climate
latitude
weather
29
primary succession can begin after
a lava flow
a forest fire
farmland is abandonded
a severe storm
30
symbiosis in which both species benefit is called
predation
mutualism
parasitism
commensalism
31
A symbiotic relationship in which one organism is harmed and the other benefits is
parasitism
mutualism
predation
commensalism
