14
What factors affect biodiversity?

1. Area, weather, niche diversity
2. Land, climate, animals diversity
3. Land, temperature, niche diversity
4. Area, climate, niche diversity

15
Catching fish at a rate faster than they can
breed is called

• a. aquaculture
• b. sustainable yield
• c. fishing limits
• d. overfishing

16
What is a species that influences the survival of
many other species in an ecosystem?

1. Important species
2. Keystone species
3. Irreplaceable species
4. Renewable species

17
The contamination of Earths air, land, or water
is called

1. Extinction
2. Aquaculture
3. Pollution
4. Habitat destruction

18
The most diverse ecosystems in the world are

1. Coral reefs
2. Deserts
3. Grasslands
4. Tropical rain forests

19
If all members of a species disappear from Earth,
that species is

• Extinct
• Endangered
• Renewable
• Threatened

20
In some areas, foresters plant one three for
every tree they cut. This activity is an example
of

1. A non-sustainable approach to a nonrenewable
   natural resource
2. A sustainable approach to a nonrenewable natural
   resource
3. A non-sustainable approach to a renewable natural
   resource
4. A sustainable approach to a renewable natural
   resource

21
The most effective way to preserve biodiversity
is through

1. Habitat fragmentation
2. Habitat destruction
3. Habitat preservation
4. Captive breeding

22
Taxol, which originally came from Pacific Yew
trees, is a medicine, that is used to fight

1. Heart disease
2. Kidney disease
3. Cancer
4. Diabetes

23
A disease kills most members of a plant species
in an ecosystem. Several animal species feed on
that plant species. After a time, the populations
of those animal species decline. Which of the
following inferences is valid?

1. The ecosystem will soon recover
2. The plant species will become extinct
3. The plant species is a keystone species in that
   ecosystem
4. Several animal species in the ecosystem will
   eventually become extinct

24
The illegal killing or removal of animals from
their habitats is called

1. Animal destruction
2. Poaching
3. Contamination of species
4. Niche diversity

25
Explain how habitat destruction affects species.

• Species lose the places where they feed, breed
  and nest. If they cant find a substitute niche,
  they must move t a new location to survive. If
  they cant relocate, they will not survive.

26
Describe the importance of biodiversity to drug
research.

• Almost half of all medicines sold today have
  chemicals originally found in wild organisms.
  Many organisms have potential medical uses that
  have not been discovered yet. The more diversity
  that exists, the more potential for sources of
  disease-fighting drugs.

27
On a personal level, what kind of decisions can
you make related to protecting an environment?

• Shorter showers
• Turn off water before brushing teeth
• Use bins for recyclables at home
• Use scrap papers to write notes
• Whenever possible, use bikes
• Carpool

28
What is the difference between clear cutting and
selective cutting of a forest?

• Clear cutting is the process of cutting down all
  the trees in an area at once.
• Selective cutting is the process in where some
  trees are cut and some are left uncut.

29
Describe how environmental decisions are made.

• By considering the viewpoints of many different
  people and weighing the costs and benefits of
  different solutions.

30
What might happen to a fish population over time
if all the largest fish in the population were
caught? Explain.

• If all the largest fish in a region were caught,
  the average size of the fish may become smaller
  over time.

31
Why is forest considered a renewable resource?

• Because new trees can be planted to replace trees
  that are cut down, forests can be renewable
  resource.

32
Explain how human population growth affects
resource use and pollution.

• As the number of humans increase, they use more
  resources, which can reduce resources
  availability and contribute to pollution, such as
  air pollution that is produced when fossil fuels
  are burned.

33
How could the extinction of a species today
affect your life in 20 years?

• The species might have been the source of a
  medicine or had another use that is unknown
  today. The species might have been important to
  the survival of another species.

34
Why are many human medicines made from chemicals
that come from plants?

• Many plants produce chemicals that ward off
  diseases and parasites. These chemicals often
  have disease-fighting properties in humans.

35
Why is a gene pool diversity important to
survival of a species?

• Species with gene pool diversity are better able
  to adapt to changes in the environment.

36
You are walking in a clear-cut part of a forest a
few days after a heavy rainstorm. A nearby stream
is very muddy and has many dead fish. What might
have happened?

• Without tree roots to hold water and soil in
  place, large amounts of soil were washed into the
  stream during the rainstorm. The soil in the
  water has made it more difficult for fish and
  other aquatic organisms to live.

37
Would you expect to find great biodiversity in
the tundra biome? Why or why not?

• No, the tundra biome growing season is too short
  to be able to provide a year-round food source
  for organisms.

38
How can habitat be preserved?

• The best way is to protect the whole ecosystems
  instead of a single ecosystem. Protecting the
  whole ecosystem saves not only endangered
  species, but also the species they depend upon
  and those that depend upon them.

39
Do you think that scientists have identified all
the wild plants that may have medical uses? Why
or why not?

• No, many parts of the rain forest remain
  unexplored so its likely that there are
  medicinal plants to be discovered.
