BIO152 Exam 5 UPDATED Exam Questions
and CORRECT Answers
Type I (survivorship curve) - CORRECT ANSWER - A pattern of survival over time in
which there is high survival throughout most of the life span, but then individuals start to die in
large numbers as they approach old age
Type II (survivorship curve) - CORRECT ANSWER - A pattern of survival over time in
which there is a relatively constant decline in survivorship throughout most of the life span
Type III (survivorship curve) - CORRECT ANSWER - A pattern of survival over time in
which there is low survivorship early in life with few individuals reaching adulthood
Type I - CORRECT ANSWER - This type of survivorship curve is exhibited by humans
and most primates.
Type II - CORRECT ANSWER - This type of survivorship curve is exhibited most
commonly by birds.
Type III - CORRECT ANSWER - This type of survivorship curve is exhibited by trees,
marine invertebrates, and most fishes.
fecundity - CORRECT ANSWER - the potential reproductive capacity of an individual
within a population. So basically: if an individual has as many offspring as possible, this value
measures how many offspring would be produced.
inversely - CORRECT ANSWER - In animals, fecundity is (directly/inversely) related to
the amount of parental care given to an individual's offspring
demography - CORRECT ANSWER - The statistical study of population characteristics
and dynamics
, (population) density - CORRECT ANSWER - The number of individuals within a specific
area or volume
larger - CORRECT ANSWER - Which kind of population is usually more stable: a larger
one or a smaller one?
decreases - CORRECT ANSWER - Population density usually (decreases/increases) with
increasing body size.
uniform (distribution) - CORRECT ANSWER - Distribution where populations are spaced
evenly. Often seen in territorial animals and plants that secrete substances inhibiting the growth
of nearby individuals.
allelopathy - CORRECT ANSWER - The production of chemicals by plants that inhibit
the growth of neighboring plants
random (distribution) - CORRECT ANSWER - Distribution in which the location of
members in a population is totally random; location of each individual is determined by chance.
Common in plants that use the wind to disperse their seeds, like dandelions.
clumped (distribution) - CORRECT ANSWER - A distribution in which individuals are
found in groups or patches within the habitat. Commonly seen in animals that travel in groups.
Also seen in plants that drop their seeds, like oaks with acorns.
(the population is) stable - CORRECT ANSWER - If the birth rate equals the death rate,
which of the following is true? Choose ONE.
- the population is increasing
- the population is stable
- the population is decreasing
