9
tiny, free-floating organisms are called?

most likely
accounts for the change in the frog's population?

not
belong?
flood or fire

12
What is the best explanation for why plants are used to
create new forms
of fuels?
to prevent overuse of non-renewable resources
increase the use of non-renewable resources
decrease habitat fragmentation
so humans can spend less money at the gas pump
13
What kind of changes has been caused by climate change?
gradual and sudden changes in temperatures
temperature and permanent changes only
sudden seasonal changes only
minimal and temporary changes only
14
What causes the population size to
decrease
? Check all that apply.
Emigration
Birth rate
Immigration
Death rate
15
Which graph represents a logistic curve?
2
1
neither
1 and 2
16
Why is human-produced carbon dioxide a huge problem?
because it causes gases released in the atmosphere to cool down earth
because it increases the rate of photosynthesis
because it increases oxygen levels in the ocean
because the global temperature is rising an average rate of 0.15 o F
17
Sun, wind, and soil are all examples of
nonrenewable resources
fossil fuels
renewable(plentiful in nature) resources
I don't have a clue!
18
Why are there little to no aquatic plants and phytoplankton below 6,000 meters? See image!
because the salt concentration
the temperature is very low below 4000 meters
because photosynthesis occurs only in the aphotic zone
because light does not penetrate past 200m
19
Which graph represents an exponential curve?
1
1 and 2
2
neither
20

in a population
per unit area
population census
biodiversity
population density
ecosystem
21
Which factor(s )will cause a population to grow exponentially?
unlimited resources
high birth rate
no predators
fierce competition
22
Desalinization creates freshwater from both seawater and brackish water. What are the impacts on nearby oceans?
overpopulation of marine life
loss of non-renewable resources and minerals
loss of biodiversity and instability in the feeding relationships
disrupt the water cycle causing global weather pattern changes
23
Which of the following would be the most effective in protecting our planet?
use plastic products
using an SUV, public transportation
purchasing paper products
widespread use of solar energy products to reduce fossil fuel emissions
24
Which body of water is nutrient rich?
coastal water
gosh, I don't have a clue!
freshwater
open water
25

Both A and B
26
Which LF does
not
belong?
spraying pesticides
drought
change in climate or temperature
introduction of invasive species
27
Individuals of the
same species
that inhabit an ecosystem at the
same time?
biodiversity
population
community
ecosystem
28
How do you know when a population has reached its carrying capacity?
the death rate increases more than the birth rate
the birth rate increases more than the death rate
the population size grows rapidly with no signs of slowing down
the population size remains steady as it near its max capacity
29
