B. carnivores
C. scavengers
D. producers
26. Which pair shows mutualism?
A. squirrel –builds nest—oak tree
B. bee – pollinating flower – feeds on flower nectar
C. spider – spins web – pine tree
D. tapeworm – intestines – food

dioxide in the atmosphere?

D. stays the same throughout the food chain
A.

30. The graph below shows a population that has reached its
A. growth potential
C. carrying capacity
B. exponential growth
D. biotic potential
31. A relationship between a consumer and producer is best
illustrated by
A. a snake eating a rodent
B. a venus-fly trap eating an insect
C. a bird eating an insect
D. a zebra eating grass
32. Red-cockaded woodpeckers and long leaf pines were once
found in abundance in NC. Now they are declining due to
A. pollution
B. they found a better habitat
C. DDT
D. habitat destruction
33. What is the main suspected environmental problem
associated with the burning of fossil fuels?
A. depletion of fresh water
B. global cooling
C. depletion of ozone
D. global warming
34. Which of the following global concerns is indirectly
responsible for all the others?
A. waste disposal
B. resource depletion
C. overpopulation
D. poor sanitation
35. An increase in pesticide use has resulted in a decrease in
the local bat population. Which of the following is the
best explanation for the decreased bat population?
A. bat food supply decreased
B. infection destroyed most of the bat population
C. many bats moved into the area
D. bat food supply increased
36. Which statement describes why pesticides are said to “move up
the food chain”?
A. pesticides have a greater effect on larger animals than on
insects
B. top predators often accumulate the pesticides contained in
the bodies of their prey
C. birds and predatory mammals are not affected by pesticides
D. pesticides kill insects and other target pests before they can
absorb the poison
37. Land and water absorb the sun’s energy when it reaches the
earth’s surface. The Earth in turn radiates some of its warmth back
out toward space. However, certain gases in our atmosphere are
able to trap this warmth and keep it from escaping into outer
space. This process is called the greenhouse effect. Carbon
dioxide is one example of these heat trapping gases. From this
information, what can you infer?
A. human activities that release more carbon dioxide into the
air may result in higher global temperatures in the future.
B. If carbon dioxide levels in the atmosphere continue to rise,
more and more heat will escape into space and global
temperatures will fall.
C. Without greenhouse gases in our atmosphere, temperatures
on earth would be significantly warmer.
D. It is called the greenhouse effect because carbon dioxide is
an important nutrient for plants in greenhouses
