9
What is the key difference between parasitism and predation?
A predator may not catch its prey but a parasite always does
Parasites don't always hurt their hosts

How do you "win" at natural selection?
go extinct
survive
survive & reproduce
16
In this picture, the grasshopper could also be called...
An omnivore
A herbivore
An autotroph
A carnivore
17
In natural selection, humans select the variations of traits to be passed down to offspring.
false
true
18
Analogous structures share
Similar function but different structure
Similar function and structure
Heterozygous structures
Similar structure but different function
19
Interspecies Competition
Between members of different species
Between members of the same species
20

21
In this food chain, what is the primary producer?
Arrows
Grass
Fox
Rabbit
22
Mutualism, commensalism, and parasitism are the three types of
prey adaptations
symbiotic relationships
competition
predation
23
What would happen in this food chain if the grass disappeared?
The number of rabbits would increase
The number of foxes would increase
The number of grass would increase
The number or rabbits would decrease
24

do not show
show
absolutly show
positively show
25
Lemark came up with the concept of Acquired Characteristic. Which is true about Acquired Characteristics?
all of the above
can be a learned skill, such as reading
comes from an experience, such as an accident
Develops after birth
26
What is the "10% rule" for energy pyramids?
Total biomass decreases by about 10% at each successive level.
About 10% of energy available at one level is available at the next level.
The number of organisms decreases by about 10% at each successive level.
Total biomass increases by about 10% at each successive level.
27
Darwin's first observations of natural selections involved:
birds
jaguars

TRUE
FALSE
36
