Unit 1 EXAM 9/16/10
Standards: 6. c. Students know how
fluctuations in population size in an
ecosystem are determined by the relative
rates of birth, immigration, emigration,
and death.
6. e. Students know a vital part of an
ecosystem is the stability of its producers
and decomposers.
6.b. Students know how to analyze
changes in an ecosystem resulting from
changes in climate, human activity,
introduction of nonnative species, or
changes in population size.

For Exam on 9/16/10
1. What is the most common explanation for population
growth by a non-native (invasive) species? Recall that
invasive species are organism not normally found in the area

Wednesday - Local and federal legislation have placed limits on the amount of nitrogen-containing fertilizers to
be tolerated in field run-offs into a lake. The reason for this legislation is that run-off of the fertilizers would
most likely produce _______.
A increased algae growth.
C evaporation of ground water.
B more acidic lake water
D fertility of predatory fish.
Explain what would happen next to the oxygen levels available for fish.
Thursday - While visiting a history museum in Montreal, Danielle observes a graph on display that records the
number of lynx (predator) and hare (prey) trapped in the Hudson Bay area between the years 1845 and 1935.
The graph has two different lines one each for lynx and hares. She notices that the two lines on the graph
follow a pattern. Which pattern does she observe?
A. Both hare and lynx populations remain constant.
B. Both hare and lynx populations rise and fall together.
C. The hare population decreases shortly after the number of lynx decreases.
D. The lynx population decreases shortly after the number of hares decreases.
Explain.
Friday - Which organism/s is affected negatively by increased temperatures? Explain.
Identify the areas on this logistic growth curve labeled a, b, and c
A FEW MORE REVIEW QUESTIONS
FOR EXAM ON 9/16/10
1. What is the most common explanation for population growth by a non-nave (invasive)
species? Recall that invasive species are organism not normally found in the area and may
have been introduced into an area by humans. The invasive species find unoccupied
niches where competition pressures are low.
2. A community of organisms interacting with abiotic environmental factors is called a(an)
Ecosystem.
3. A group of similar-looking organisms that breed with each other and produce fertile
offspring make up a(an) species and a(an) population if they live in the same area.
4. The ultimate source of energy for life on Earth is the sun.
5. What is the variety of species in a given area called? biodiversity
According to the food
web:
6.Which organism(s) is a carnivore?
Snake, hawk, and lizard
7. Which organism(s) is an omnivore?
Mouse and bird
8. Which organism(s) is a herbivore?
Ants, chipmunk, and grasshopper
9. Which organism(s) is a producer?
Cactus and shrub
10. A top predator may increase the diversity of species
lower on the food chain by decreasing competition
amoung the survivers.
10. List three reasons why habitat protection is important.
Species do not live independently.
Protecting habitat protects species
Without habitat, the balance of nature could be disrupted.
11.In Sacramento, automobile exhausts cause dirty, brown haze known as smog.
12. Ecosystem connectivity must be considered because human pollution travels by wind,
river, and ocean currents.
