An investigative technique, “mark-recapture,” was
used to estimate the bog turtle population in
several meadow bogs. Four bog turtles were
captured and marked in July. Six bog turtles were
captured in August—four of which were marked.
Five marked bog turtles were captured in
September. What is the best estimate of how
many turtles live in the bogs?
A. 4
B. 5
C. 6
D. 7
What shape would a growth curve look like when a
population approaches the carrying capacity for
that population?
A. J
B. L
C. S
D. V
Global warming is affecting Earth in many ways:
temperatures are rising, icebergs are melting,
and ocean waters are covering our beaches.
Which abiotic factor of global warming affects
organisms in coastal areas the most?
A. ocean levels rising over beaches
B. redistribution of ocean organisms
C. decreased temperatures of ocean water
D. increased competition among ocean
organisms
Deer at Stone Mountain State Park appear to be
thin and under-nourished, and most leaves are
gone from low-growing plants. A park ranger
says an average of three dead deer per day are
removed from the park, having potentially died
from starvation. Which environmental factor has
been exceeded?
A. food web
B. biotic potential
C. carrying capacity
D. predator population
Populations of brook trout feed on mayflies and
the trout are often eaten by raccoons, unless they
can hide under overhanging plants or under rocks.
An extended period of hot weather decreases the
amount of dissolved oxygen and increases the
water temperature to 75°F, levels unsuitable for
trout survival. What abiotic factors may be
affected most by the hot weather?
A. rocks, sunlight, water
B. mayflies, plants, rocks
C. mayflies, raccoons, trout
D. dissolved oxygen, temperature, water
Which is a limiting factor in a population of
panda bears?
A. a decrease in disease
B. a decrease in birth rate
C. an increase in birth rate
D. an increase in bamboo forests
A quadrant study is set up in the school’s environmental
center to study the density of milkweed plants. Using a
three-foot square quadrant, ten areas are sampled,
obtaining the following data:
number of plants: 3, 4, 2, 4, 3, 2, 3, 2, 3, 4
Using the formula, population density = number of plants /
unit area, what is the density of milkweed plants in the
field?
A. 1/3 plant per square foot
B. 1/2 plant per square foot
C. 3 plants per square foot
D. 4 plants per square foot
Which is the best example of an abiotic factor that
would impact an ecosystem?
A. prey
B. Seeds
C. Sunlight
D. predators
