BIOL 301 FINAL (PREVIOUS QUIZZES)
net primary productivity is calculated as - Correct Answers -GPP - respiration
units of GPP - Correct Answers -kJ/m2/y
which of the following factors is NOT used for quantifying primary productivity over
time? - Correct Answers -change in consumer biomass
Which is the portion of energy that an organism uses to maintain its body temperature?
- Correct Answers -respired
Terrestrial NPP is greatest in _____ ecosystems, and aquatic NPP is greatest in _____
ecosystems. - Correct Answers -tropical; coastal
Between latitudes of 30° N and 30° S, NPP is primarily constrained by - Correct
Answers –precipitation
in the sonoran desert of arizona, young saguaro cacti often begin life in the shade of
mesquite trees, they usually die if they began life in out in the open. this is an example
of - Correct Answers -facilitation
which of the following is true about succession - Correct Answers -Species richness
initially increases with time in terrestrial succession.
You observe three beech-maple forests in Indiana that began as ponds. How might you
determine whether they all started succession with the same community composition?
A) carbon-date the maple and beech trees to see how long they have been living; older
trees would suggest a more diverse starting community
B) calculate the species diversity of lichens found on the trees
C) try growing different types of pioneer species at each site
D) sample the soils at each site for pollen and carbon-date them to get an estimate of
the species that appeared first at the site - Correct Answers -sample the soils at each
site for pollen and carbon date them
,In aquatic ecosystems, trophic pyramids of biomass are inverted because - Correct
Answers -the standing biomass of algae is lower than the standing biomass of
consumers
Assimilation energy is the percentage of consumed energy that is - Correct Answers -
digested and absorbed
Aquatic ecosystems typically have ¬¬¬¬¬_____ trophic levels, while terrestrial
ecosystems typically have _____ trophic - Correct Answers -5; 3-4
A trophic level has a biomass residence time of 5 years and net productivity of 3
kg/m2/y. What is the biomass in the trophic level? - Correct Answers -15 kg/m2
Chose a logical path for a molecule of water starting and ending in the atmosphere. -
Correct Answers -precipitation, infiltration, evaporation, condensation
Which statement is TRUE about the global hydrologic cycle?- Precipitation is greater
than evaporation in terrestrial ecosystems. - Correct Answers -Precipitation and
evaporation are about equal in terrestrial ecosystems
In waterlogged conditions, anaerobic metabolism of carbon compounds can cause the
production of the greenhouse gas - Correct Answers -methane (CH4)
Nitrogen-fixing plants such as soybeans are able to convert - Correct Answers -
atmospheric nitrogen to nitrate and ammonium
Which is NOT an example of a major human alteration to the global nitrogen cycle? -
Correct Answers -Animal waste from agriculture
Dead zones are formed when rivers that empty into oceans carry excess phosphorus
and nitrate runoff. These dead zones are caused by - Correct Answers -algal blooms
Which of the following does NOT significantly affect terrestrial decomposition rates? -
Correct Answers -phosphorus content of litter
Decomposition is more rapid in _____ forests because of _____. - Correct Answers -
tropical; increased temperature and precipitation
In the study of leaf decomposition in a stream in Germany using leaf litter enclosed in

a fish that has tissue solute concentrations that are higher than surround waters -
Correct Answers -is hyperosmotic; trying to not drink the environmental water in attempt
to maintain internal water concentrations
photosynthesis occurs in two steps known as ___ and the ____ - Correct Answers -
light; calvin
why are both CO2 and O2 limited in aquatic environments? - Correct Answers -not very
soluble in water
a smallmouth bass swimming in cold water of a springtime lake would likely expend
______ energy than when swimming in warmer water of lake during the summer -
Correct Answers -more
