2 What shape is exponential
growth and what causes it?
• “J”
• Unlimited resources
(food, water & space)
3 Draw and describe exponential
growth.
• Slow initial growth that becomes rapid
over time.
4 What is the shape and causes of
logistic growth?
•“s”
•Exponential
growth that
slows or stops
because
of limited
resources
5 Draw and describe logistic
growth.
• Exponential growth that slows or stops
because of
limited
resources
6 What is the largest number of
organisms of a species the
environment can support?
• Carrying Capacity
7 What types of factors are
considered limiting factors that
restrict population growth?
• Biotic and abiotic that restricts population
growth (ex. Food (biotic) & space (abiotic))
8 What is density?
• Amount of organisms in an area
9 What are the two types of limiting
factors?

11 What are the three types of
density-independent factors?
• -Natural Disaster
• -Weather / Climate
• -Human Activity
12 In the water cycle, what two
methods take water into the
atmosphere and briefly
describe each.
• -Evaporation- From areas of concentration
of water (Ponds, lakes etc.)
• -Transpiration- H20 lost from plants
13 What is it called when water
forms clouds?
• Condensation
14 What is it called when water
falls back to Earth and give 2
examples.
• -Precipitation
• -Rain
• -Snow
15 What four methods release
carbon dioxide/CO2 to the air?
•
•
•
•
-Volcanoes
-Human Activity
-Respiration
-Decomposition
16 What process uses carbon
dioxide to make glucose?
• Photosynthesis
17 Organisms use and release
carbon dioxide by which
process?
• Respiration
18 What 2 important uses is carbon
dioxide needed for to help
humans?
• -Food carbohydrates
• -Living tissue and skeleton
19 What converts N2 in the soil for
plants?
• Bacteria
20 When organisms consume
plants, what macromolecule does
nitrogen help produce?
• proteins
21 What three factors help return
nitrogen to the soil?
• -Dead organisms/ decompositions
• -Bacterial nitrogen fixation
• -Animal Waste
22 What breaks N2 down in the soil
and returns it to the
atmosphere?
• Bacteria
23 Amino acids are monomers of
which macromolecule that is
vital to humans?
• Proteins
24 How much of the atmosphere is
nitrogen?
• 78%
25 What saves/protects natural
resources and organisms?
• Conservation Biology
26. How many species are in
danger of extinction in the
U.S.?
• 1,200
27 An organism that is likely to
become endangered in the near
future is considered? Give an
example
• -threatened Species
• -Polar Bear
28 An organism that is subject to
immediate extinction is
considered? Give an example.
• -Endangered Species
• -Humpback Whale
29 What is a study over a long
period considered?
• Longitudal Analysis
30 What is an increase in the
average temperature on Earth?
• Global Warming
31 What is the trapping of heat in
the atmosphere? What are 2
implications?
• Greenhouse Effect- Deterioration of habit,
drought and disruption of relationships
32. The water cycle:
condensation, precipitation, runoff,
transpiration, evaporation, seepage
and root uptake.
33. Carbon cycle: co2 in
atmosphere, co2 in ocean add
photosynthesis.
34. What is moderate temperature
areas called?
• Temperate
35 What is called when a tree
sheds its leaves every year during
a particular season?
• deciduous
