All the members of a single species that occupy a particular area at the same time are known as a what?
Population
100
What is the term for when one species splits into two species or when one species transforms into another over time.
Speciation
100
The particular place where an organism lives is its what?
habitat
100
When too many nutrients are added to of a body of water, this is known as what?
eutrophication
100
A word I know, six letters it contains, remove one letter and 12 remains. What is it?
Dozens
200
Define microevolution and how we can observe it
Studying allelic frequency changes over time means microevolution is occurring
200
What are the two postzygotic isolating mechanisms?
Hybrid inviability and hybrid sterility
200
The total number of individuals that an environment can support is known as the what?
Carrying capacity
200
Define species richness and species diversity
Richness is the number of different species in the ecosystem, diversity is the relative abundance of each species

In my hand, I have two coins that are newly minted. Together, they total 30 cents. One isn’t a nickel. What are the coins?
Quarter and a nickel
300
What are the three types of natural selection?
Directional, Stabilizing, Disruptive
300
What are the two types of speciation and which of the two occurs because of geographic isolation?
Symaptric and Allopatric. Allopatric is geography based
300
What type of growth pattern is graph A? what type of growth is graph B
A is exponential/semelparity/opportunistic
B is logistic/iteroparity/equilibrium
300
What are the two types of succession and where to they begin?
Primary begins on exposed rock from volcanic activity
Secondary begins on soil
300
What never asks questions but is often answered?
A doorbell
400
Define and Explain both bottleneck effect and founders effects
Both are forms of genetic drift. Small group starting a new population and lucky survivors of a disaster by chance
400
Define convergent evolution and coevolution and provide an example of each.
convergent: two unrelated species converging on the same trait
coevolution: unrelated species evolving as a result of each other evolving. (evolving together)
400
Define density-independent and density-dependent factors and provide an example of each
dependent- driven by population size
independent- not driven by population size
400
Define the three types of symbiotic relationships and provide an example of each
mutualism: both benefit (pollinators and flowers)
parasitism: one benefits, one is harmed (parasites)
commensalism: one benefits, one is unaffected (barnacles and whales)
400
What breaks yet never falls, and what falls yet never breaks?
Morning and night
500
What are the five Hardy Weinberg conditions and what does it mean when all five are met?
No selection, random mating, no gene flow (migration), large population size, no mutations. When all are met, no microevolution occurs
500
List and define all five prezygotic isolating mechanisms
Habitat- living in different areas
Temporal- different mating seasons
Mechanical- genitalia does not match
Gamete- gametes are not compatible
Behavioral- different courtship
500
List and define the three types of survivorship curves
Type 1: most survive past a midpoint in life and die old
Type 2: death is linear, equally likely at any point
Type 3: few survive past a midpoint, most die young
500
Explain the flow of energy through an ecosystem. Where does it start and how does it travel?
Always begins with the producers. they are consumed and 10% of the energy is sent to the next consumer level. consumers then die and are decomposed, returning the energy as inorganic materials to the soil

What came first, the chicken or the egg?
The egg. Dinosaurs laid eggs long before there were chickens!
