Final Jeopardy
$100 Question from H1
When two organisms compete for the same resources.
$100 Answer from H1
Competition
$200 Question from H1
Includes all the resources an organism uses, including Trophic level, Habitat, Behaviors, and its role in the ecosystem.
$200 Answer from H1
Niche
$300 Question from H1
When one organism kills and eats another.
$300 Answer from H1
Predation
$400 Question from H1
When evolution of the phenotype of one species is triggered or influenced by another species.
Example: Flower shape fits mouthparts of pollinator (ex. Bee)
$400 Answer from H1
Co-evolution
$500 Question from H1
Adaptation where the physicalappearance of an organism blends in with the external environment in order to escape predators.
$500 Answer from H1
Camouflage
$100 Question from H2
A close and long-term interaction between members of two different living species
$100 Answer from H2
Symbiosis
$200 Question from H2
Relationship where one species benefits (+) by feeding upon another living host species.
Host may be weakened over time and eventual die (-).
$200 Answer from H2
Parasitism
$300 Question from H2
Relationship where one organism benefits (+) and the other organism is unaffected (Ø).
$300 Answer from H2
Commensalism
$400 Question from H2
Relationship where both organisms benefit from the interaction (+/+).
$400 Answer from H2
Mutualism
$500 Question from H2
A barnacle on a whale or a bird nesting in a tree are two examples of this type of symbiotic relationship.
$500 Answer from H2
Commensalism
$100 Question from H3
Different phenotypes for a trait found within a population are called:
V______________________
$100 Answer from H3
Variations
$200 Question from H3
Phenotypic difference that allowsthese organism to survive and reproduce more successfully than those with other phenotypes.
$200 Answer from H3
Adaptation or adaptive variation
$300 Question from H3
A variation that is “neutral” to an organism’s ability to successfully reproduce.
$300 Answer from H3
Non-adaptive variation
$400 Question from H3
An organism has dark spotted furwhich enables it to hide and escape from predators.
Which type of variation? Adaptive or non-adaptive
$400 Answer from H3
Adaptive
$500 Question from H3
Can a non-adaptive variation become adaptive? If so, how?
If not, why not?
$500 Answer from H3
Yes, if the environment changes and this variation now helps the organism survive and reproduce better than others.
$100 Question from H4
What type of selection occurs when the NATURAL environment influences which variations are able to survive and reproduce. As a result future generations show an increased frequency of that trait in the population.
$100 Answer from H4
Natural Selection
$200 Question from H4
Who directs Artificial selection, and who benefits?
$200 Answer from H4
Humans: Achieved by crossing plant or
animal species and selecting for traits useful to people!
$300 Question from H4
What pattern of selection?
$300 Answer from H4
Directional
$400 Question from H4
What pattern of selection?
$400 Answer from H4
Stabilizing selection
$500 Question from H4
What type of selection?
$500 Answer from H4
Disruptive selection
$100 Question from H5
The change in gene frequency in a population over time.
$100 Answer from H5
Evolution
$200 Question from H5
Organisms that interbreed and produce fertile offspring in nature.
$200 Answer from H5
Species
$300 Question from H5
Where would you expect to find fossilsof the oldest organisms?
A
B
C
D
E
$300 Answer from H5
E, the deepest rock layer.
$400 Question from H5
Structures that have no function in modern organisms, but were likely functional in their ancient ancestors.
$400 Answer from H5
Vestigial organs
$500 Question from H5
DNA or Amino acid comparisons show how long ago organisms shared a common ancestor (how closely related they are)
$500 Answer from H5
Molecular or Biochemical evidence
Final Jeopardy
4 steps of Natural Selection
Final Jeopardy Answer1. Variation in the population2. Competition for limited resources,
environment selects for the best adapted3. Differential reproduction (some survive
and reproduce more than others)4.4. Result:Result: change in gene frequency in the
population over time (evolution)
