ASU BIO 182 Exam 3 Verified Questions And Answers
With Updated Study Tests
Which group is not a population?
all four groups are populations
How would you estimate the number of whales in a population?
mark and recapture
What is a population?
a group of individuals of the same species living in the same area at the same time
True or False? Sampling quadrats would be the better method for estimating the number of whales in a
population.
false
True or False? Mark and recapture would be the better method for estimating the number of saguaros in a
population.
true
True or False? The shrinking population between 1965 and 1970 could have resulted from a decrease in the
birth rate or an increase in the death rate.
true
True or False? The growing population between 1985 and 1995 could have resulted from a decrease in
emigration or an increase in immigration.
true
,The human population has grown ____________________
exponentially
The growth of a population depends on __________________
the birth rate minus the death rate.
A population stops growing when it _____________________
reaches its carrying capacity.
True or False? The carrying capacity of a population depends on the resources available in the environment.
true
Why do bluegills nest on the edge of the lake?
The habitat in the shallow water might receive more solar radiation, holds more zooplankton (which is what
they eat), more protective over young than it in deeper water where larger fish reside, more algae for the fish to
hide in, warmer water for embryos to develop quickly and enhance survival/fitness.
Activity: Write a Figure Legend
Bluegills prefer certain water temp; when given a choice between 27 degrees celsius and 31 degrees celsius,
bluegills spent a majority of their time at 31 degrees celsius.
True or False? If males compete for space, a large male will likely force a small male to spend less time on the
side of the tank with the optimal temperature.
true
, True or False? Both models assume that no individuals immigrate into the population.
false
t/f: When possible, a bluegill prefers to have a body temperature around 31°C.
true
T/F: When competing with an adult, a juvenile bluegill will always have a lower body temperature than its
preferred temperature.
False (If the environment hotter than preferred, on average, large bluegill will force small bluegills to remain in
parts of water that are hotter than preferred)
T/F: All else being equal, the carrying capacity of a lake would likely increase as more parts of the lake warm
to 31°C.
true
T/F: All else being equal, a juvenile bluegill will likely grow slower in a lake with many adult bluegills than in
a lake with few adults
true
T/F: The growth of a bluegill population would be better described by a model without density dependence
than by a model with density dependence.
false, Because access to suitable temperatures is limited, the growth of the population will have a carrying
capacity, which requires density dependence
T/F: The number of whales was more likely estimated by sampling than by mark-recapture.
