11
Looking at the ecological pyramid, what would be the most likely number of joules to fill in x, y, and z?
x =10,000; y =1,000; z =10
x =1; y=500; z =10,000
x =100; y =1,000; z =10,000
x =10,000; y = 500; z =1
12
Which is NOT a part of the carbon cycle?
photosynthesis
combustion
transpiration
extracion
13
Which is the best description of evolution?
the growth of an individual from birth to adulthood
the genetic change within a population over one generation
the increased reproduction of a population
the genetic change within a population over time
14

B
A
C
D
15
Where is upwelling most likely to occur?
along the east coast of a continent
along the west coast of a continent
in the center of ocean basins
along the equator
16
Which is used to measure the diversity of an ecosystem?
Species richness only
species richness and evenness
species extinction rate, richness, and evenness
species evenness only
17

India
Russia
Nigeria
Canada
18
Which is NOT an example of a fast process of the carbon cycle?
sedimentation
combustion

photosynthesis
19
Choose the correct sequence for energy flow within an ecosystem
producers--> carnivores--> herbivores--> carnivores
herbivores --> producers--> carnivores --> scavengers
producers--> herbivores--> carnivores--> scavengers
scavengers--> producers--> herbivores--> carnivores
20
The table lists the number of individuals of each species. Which community is most diverse overall?
Community 1
Community 2
Community 3
Community 4
21
Boreal forests tend to have a thick layer of organic material but the soil is poor in nutrients. Why?
Low precipitation rates and cold temperatures slow decomposition.
The rapid growth rate of plants uses the nutrients rapidly.
The organic material is low in nutrients.
The soils have a low permeability and the nutrients do not dissolve
22
Rapid growth occurs during which phase of demographic transition
4
3
1
2
23
Which is a density-independent factor that could limit the size of a population?
an increase in a predator population
low population numbers
the accidental spill of a pesticide that causes the population to decrease
the reduction of a competitor species
24
When interspecific competition occurs between two species with the same realized niche
the two species will engage in resource partitioning.
the two species will form a symbiotic relationship.
one species will perform better and drive the other to extinction.
the two species will engage in commensalism.
25
In a closed system
entropy does not occur.
there are no matter and energy exchanges across system boundaries.
inputs are frequent but outputs are rare.
matter and energy exchanges occur across system boundaries only rarely.
26
Why do tropical rainforests, deep ocean habitats, and deserts all support differing numbers and abundances of plant life
Each biome has limited space to support abundant plant life.
The biomes have extreme temperature fluctuations that may harm plants.
Biomes receive varying amounts of solar energy for photosynthesis.
Herbivores eliminate plant species in certain biomes.
27
The second law of thermodynamics states that
no energy is lost in an energy conversion.
matter can be neither created nor destroyed.
velocity increases as a dropped object nears Earth’s surface.
all systems move toward increased entropy.
28
If two similar species each occupy a smaller niche when they live together than they would if they lived alone, they are
coevolving.
increasing niche overlap.
involved in succession.
partitioning resources.
