NOTE: If you have an IEP and you are (a) taking your test in another location, (b) you think you might want
extended time, or (c) you have special needs for your tests with regard to choices, etc, YOU MUST LET ME
KNOW TODAY! Modifications need to be made PRIOR to you sitting down for the test (i.e. you may not start
the test in class during EnviSci and finish it another day without appropriate modifications!)

you need them!
Question
Answer
ORGANISM

POPULATION

1) What is the correct order of levels of organization?
COMMUNITY  ECOSYSTEM  BIOSPHERE
2) Describe what a graph would look like if a population has
exponential growth (the shape).
J SHAPED
3) Describe what a graph would look like if a population has
logistic growth (the shape).
S SHAPED
4) What are the three types of population distributions? Draw a
pic of each…use dots to represent individuals.
A

B
C
5) If a scientist can’t physically count each organism in a
population, what technique might he employ to estimate the
size?
6) Name three abiotic factors.
SAMPLING TECHNIQUES
7) Name three biotic factors.
PLANTS, ANIMALS, MICROORGANISMS
8) Name three density-dependent factors.
COMPETITION, PREDATION, DISEASE
9) Name three density-independent factors.
EARTHQUAKE, TORNADO, MUDSLIDE
10) What is the equation for determining population growth?
(IMMIGRATION + BIRTHS) – (EMIGRATION
+ DEATHS)
11) In one year in a population of 100 squirrels, 12 die of natural
causes and 22 are born. Seven juveniles leave the population
to establish territories elsewhere, and 4 new individuals arrive
from a different patch of forest. What is the growth rate of
the population per 100 individuals?
12) What is the % growth for the previous question?
(4 + 22) – (7 + 12) = 26 – 19 = 17
13) Name the three types of survivorship curves and an example
of an organism in each.
TYPE I – HUMAN
TYPE II – BIRD
TYPE III - FROG
MOSTLY YOUNG; GROW
14) What does an age structure diagram that is pyramidal show?
(Mostly young or old?) Will this population grow, stay the same,
or decline?
15) What does an age structure diagram that is the same width
top to bottom show? (Mostly young or old?) Will this
population grow, stay the same, or decline?
16) What does an age structure diagram that is top-heavy show?
(Mostly young or old?) Will this population grow, stay the same,
or decline?
WEATHER, ATMOSPHERE, LIGHT
17%
SAME NUMBERS OF OLD AND YOUNG;
STAY THE SAME
MOSTLY OLD; DECLINE
