Test Description: MM
Instructions: Answer all questions to get your test result.
1) Indicator species act as early warning systems for environments. All of the following are characteristics of indicator species EXCEPT...
A
resistant to environmental stressors
B
located withing the environment
C
accessible for frequent monitoring
D
sensitive to environmental stressors
2) A massive flood strikes a forest ecosystem without warning. What will happen to the organisms in the ecosystem?
A
Most organisms evacuate the flooded area.
B
Most organisms adapt to the wet environment.
C
Most organisms drown in the flood waters.
D
Some organisms evacuate, while others die in the flood waters.
3) An Arctic climate historically receives snowfall 10 months of the year. Some rabbits have white fur, while other rabbits have fur that changes color during the warm months. Over time, it snows only 6 1/2 month a year. Which trait is most favorable
A
Brown fun is more favorable because the rabbits spend a majority of the year without snow.
B
Light tan fun is more favorable because the rabbits can blend into any environment.
C
White fur is more favorable because the rabbits spend a majority of the year in snow.
D
White fur that changes to brown during the warm months is more favorable because the rabbits can be camouflaged all year long
4) Which situation does Not require and organism to adapt due to an environmental change?
A
climate change
B
deforestation
C
ice age
D
flooding
5) Why is a short-term environmental change more likely to negatively affect a population than a long-term change?
A
Animals always move away and leave the ecosystem with less biodiversity.
B
Animals always die.
C
Animals do not have time to adapt.
D
All of the above.
6) A class of science students investigates and records short-term effets of a tornado that destroyed an area near the school. Which change was NOT caused by the tornado?
A
future populaitons with inherited traits suffer from disease and malnutrition
B
species of squirrels became extinct
C
trees were knowcked down
D
future populations inherit traits that allow for survival in the new environment
7) How are future populations affected by long-term environmental change?
A
Future populations pass on fewer inherited traits.
B
Future populations inherit feeding patterns.
C
Future populations with inherited traits suffer from disease and malnutrition.
D
Future populations inherit traits that allow for survival in the new environment.
8) Hurricane Katrina caused a massive amount of flooding that affected many species of terrestrial life. How would a population of terrestrial animals survive this natural disaster?
A
The population cannot escape a sudden flood.
B
The population must flee to higher land or perish.
C
None of the above.
D
The population can adapt to become marine animals.
9) A scientist wants to research the impact climate change has had on one species native to the area. What information would be most useful to measure?
A
The types of species in the area
B
The number of producers in the area
C
The types of organisms in the area each year
D
The population of the species in the area each year
10) Pollution can have an effect on organisms and the environment. What is an effective way to reduce the amount of pollution on Earth?
A
Sink trash and waste in the ocean
B
Recycle trash and waste
C
Burn trash and waste
D
Bury trash and waste
11) Why is history important in gauging the effects of an environmental change on organisms?
A
History cannot be used to determine changes in the environment because of data source reliability.
B
Scientists use data to disprove historical trends.
C
Scientists develop new theories without consulting previous research and data.
D
Scientists examine how generations of organisms change.
12) How would global climate for organisms be affected by a volcanic eruption?
A
Particulate matter in the atmosphere would trap solar radiation and decrease global temperatures.
B
Particulate matter in the atmosphere would reflect solar radiation and decrease global temperatures.
C
Wildfires caused by the particulate matter would increase global temperatures.
D
Increased precipitation caused by particulate matter would increase global temperatures.
13) Plate movement separated species of organisms. This isolation lead to...
A
species developing similar traits to allow survival in different environments
B
species acquire learned behaviors due to the separation
C
species inheriting different traits that caused extinction due to the separation
D
species developing different traits to allow survival in different environments
