Answers
1
How do greenhouse gases support life on Earth?
they form carbon dioxide, which is absorbed by fossil fuels
they absorb UV radiation, which keeps the surface warm
they pass sun energy to plants for photosynthesis
they absorb infrared radiation, warming the surface
2
How might an introduced plant species kill a native plant species?
its rapid growth can deprive native plants of food
its rapid growth can deprive native plants of carbon dioxide
its rapid growth can deprive native plants of sunlight
it can cause soil loss from erosion
3
Which freshwater zone is muddy and sandy and is home to many decomposers?
pelagic
benthic
limnetic
littoral
4
Which term describes managing resources responsibly for current and future needs?
habitat fragmentation
species introduction
biomagnification
sustainable development
5
How is a microclimate different from climate?
microclimate is the climate of a small, specific space
microclimate is a short-term pattern of weather conditions
microclimate is climate during a specific season
microclimate is the climate that affects microbes
6
Which law regulates emissions from automobiles and industrial factories?
Clean Air Act
National Environmental Policy Act
Endangered Species Act
Clean Water Act
7
What distinctive feature characterizes an
estuary
?
lack of biodiversity
a mix of freshwater and salt water
strong currents and waves
lack of nutrients in the water
8
What do temperature, sunlight, water and wind have in common?
they determine an area's climate
they are all biotic factors
they make up the biota of the biosphere
their long-term variations determine weather
9
What does the Endangered Species Act do?
protects the environments of species near extinction
provides food for endangered species
protects endangered plants only
protects animals from predators
10
Why has Earth's carrying capacity for humans increased?
humans eat fewer plants than they used to
humans have displaced other organisms
humans have used technology to modify their environment
humans can live closer together than other animals
11
Why are frogs considered an
indicator species
for water quality?
they develop diseases when pollutants are present
they directly contact pollutants and show negative effects
they are easily killed by pollutants
they are able to break down pollutants
12
What is one of the greatest threats to biodiversity on Earth?
decrease in food supply
pollution
loss of drinking water
habitat destruction
13
Which level of an ecosystem feels the strongest effects from biomagnification?
primary consumers
secondary consumers
tertiary consumers
producers
14
Why can't trees grow in tundra?
precipitation is low and permafrost captures most moisture
there is not enough sunlight
their roots cannot anchor the tree in the permafrost
the average temperature is too low
15
What is global warming?
changes in the biosphere than affect the atmosphere
a trend of increasing temperatures on Earth
normal temperature fluctuations in Earth's climate cycle
melting of polar ice caps
16
How are the biosphere and biota related?
biota are the living things that inhabit the biosphere
the biosphere is a part of the biota
both are part of the hydropshere
both are part of the geosphere
17
Which ocean zone has the greatest biomass?
abyssal
neritic
bathyal
intertidal
18
What does the Gaia hypothesis explain?
how Earth's spheres are independent of one another
how plants increase the levels of carbon dioxide on Earth
how biotic and abiotic factors interact in the biosphere
how feedback loops affect the process of photosynthesis
19
What term describes the give and take between the biosphere and the Earth's other spheres?
feedback loop
biomagnification
photosynthesis
biota
20
In what ways are coral reefs and kelp forests similar?
both are in cold, nutrient rich waters
both are made up of a single species of organism
both harbor large communities of organisms
both are in warm, tropical climates
21
Why does the polar zone have the coldest climate?
lack of plant life causes heat to be lost to the atmosphere
the polar region gets the most indirect sunlight
lack of water at the poles causes land to cool
the biota at the poles absorb heat
22
Which ocean zone contains organisms that tolerate changing temperature, moisture and salinity?
neritic
intertidal
bathyal
abyssal
23
Which of the following is a non-renewable resource?
sunlight
coal
water
wind
24
Which factor does
NOT
determine the size of a person's ecological footprint?
amount of waste produced
size of population
efficiency of resource use
toxicity of waste products
25
Which ocean zone is always in complete darkness?
abyssal
bathyal
intertidal
neritic
26
In which biome would you expect to find nocturnal animals and plants with deep root systems?
tropical rain forest
taiga
grassland
desert
27
How are wetlands different from rivers?
rivers have more defined plant communities
rivers flow on land saturated by ground water
wetlands have very little water flowing through them
wetlands are not as productive as rivers
28
Why might an introduced animal species overrun native species in an ecosystem?
it is more energy efficient so it eats less food
it often has no natural enemies
it is a predator of native species
its population size is smaller than native species
29
Which earth system includes everything below Earth's surface?
hydrosphere
atmosphere
geosphere
biosphere
30
Which of Earth's systems are humans part of?
the part of the biosphere that doesn't include biota
the hydrosphere
the atmosphere
the biota portion of the biosphere
31
What determines Earth's climate zones?
the number of microclimates
both temperature and precipitation
average temperature
average precipitation
32
Why was the Alaska pipeline was built raised up on "legs" in areas of caribou migration?
to keep the pipeline from harming caribou
to keep caribou from damaging the pipeline
to prevent habitat fragmentation
to prevent caribou from migrating to the wrong habitat
33
Which of the following methods can prevent slow-growing fish populations from being depleted?
harvest reduction
fishing bans
rotation
fishing gear review
34
Why is oil considered a non-renewable resource?
