Type of symbiosis where one individual benefits while the other individual is
harmed (slowly)
100
What is parasitism
Continue
200
Occurs when one organism captures and eats another
organism
What is predation
Continue
300
This is when two organisms fight for the same limited organisms
What is competition
Continue
400
Type of symbiosis that occurs where both individuals benefit
What is mutualism
Continue
500
The type of symbiosis that occurs when one organism
benefits and the other organism is neither benefited nor harmed

600
In the “Modeling Predation” lab, we modeled predation after an algal bloom and after a spawn. In our
model, a __________was hunting for __________.
What is heron, fish
Continue
700
Certain species of mites will live on the bodies of flies (mostly for
transportation). The mite makes flight more difficult for the fly and also
affects its aerial hunting ability. This interaction is _________
Continue
What is parasitism
800
Oxpeckers are birds that run over the backs of hippopotami and rhinoceroses.
These birds rid their partners of injurious and annoying pests and in
doing so obtain a ready supply of food. This is an example of _______________
What is mutualism
Continue
900
Humans have Demodicids (eyelash mites) that feast on oil secretions and
dead skin. We don’t know they are there. This is an example of ___________.
What is commensalism
Continue
1000
This is the difference between an ectoparasite and an endoparasite.
What is endoparasites live within and ectoparasites
live on the outside
Continue
100
What is habitat
Continue
All of the biotic and abiotic factors that make up the area
where a species lives
200
This is an example of both an abiotic and biotic factor in “your”
environment:
What is “1 living” and “1 nonliving”…answers vary
Continue
300
Species that occupy similar niches but live in different geographical regions
What are ecological equivalents
Continue
400
When two species are competing for the same resources, one species will be
better suited to the niche…and the other will be pushed into another niche or
extinction
What is competitive exclusion
Continue
500
This is what “niche partitioning” means:
What dividing up natural resources, so that two species can “share” the niche
Continue
600
These are the three factors that make up an organism’s “ecological niche”
What are 1)food, 2)abiotic conditions, 3)behavior
Continue
700
This is one reason why it might hurt biodiversity if you move an “exotic
species” into a habitat it doesn’t currently occupy
What is “it could better adapt to the niche or have no natural predators…it could drive
native species out or to extinction [competitive exclusion]
Continue
800
Frog A lives in Madagascar and has the same nice as Frog B from South America. “This” is the reason why these frogs are NOT experiencing
competitive exclusion.
What is the frogs are not part of the SAME community (competing for same limited
resources) Continue
900
One of the factors that makes up an ecological niche; the time of day a species is active as well as where it
reproduces.
What is behavior
Continue
1000
An example of an outcome of competitive exclusion is
_________evolution where selection for a specific physical trait allows one organism to be better adapted to survive in a different “part” of the
niche.
What is divergentContinue
100
A measurement of the number of individuals living in a defined space
What is population density
Continue
200
Individuals may live in this kind of “dispersion pattern” if they are territorial or
compete for the same resources often.
What is uniform dispersion
Continue
300
In order to gain protection or help each other out more readily in accessing food and other resources, individuals within a
population may have this type of dispersion.
What is “clumped dispersion”
Continue
400
The three-toed sloth is a solitary animal, and it has no competitors
and few natural predators. It would most likely live in a __________
dispersion pattern
What is random
Continue
500
Organisms like birds, small mammals and
reptiles show survivorship roughly equal at all ages of an organism’s life.
This is which “Type” of survivorship curve
What is “Type 2”Continue
600
Organisms like salmon have this type of
survivorship
What is Type III
Continue
700
This is the type of information a survivorship curve shows
What is the number of surviving members in a population over time.
Continue
800
This is how population density and population dispersal are different
What is population density measures the number of individuals in an area (not how
they are grouped/dispersed)
Continue
900
This type of “intraspecific” interaction might cause uniform dispersion.
What is competition for limited resources
Continue
1000
Scientists might infer “this” about a deer’s habitat if the density of the deer population decreases over a
given time.
What is that resources may be depleted or community may have changed due to
arrival of a new predator
Continue
100
This is the type of growth that occurs when a population size increases dramatically
over a period of time (producing a J-shaped curve)
What is exponential growth
Continue
200
The movement of individuals out of a population into another population
What is emigration (with an “e”)
Continue
300
The maximum number of individuals of a particular species that an environment can
normally and consistently support
What is carrying capacity
Continue
400
A dramatic decline of a population over a short period of time.
What is a population crash
Continue
500
Parasitism and disease are examples of density _________limiting factors
What is dependent
Continue
600
The “kind of factor” that has the greatest effect in keeping the population numbers
LOW for any given species
What is a limiting factor
Continue
700
Aspects of the environment that limit a population’s growth regardless of
the density of the population
What is a density independent limiting factor
Continue
800
An example of a density independent limiting factor
What is unusual weather, natural disasters, and human activity
Continue
900
A population of algae in a pond is limited by the amount of sunlight that strikes the pond’s surface. Sunlight is
an example of a density _____________factor.
What is independent (unless the algae population becomes big enough to block
the sunlight)Continue
1000
A grasshopper feeds on meadow grasses. If a fire burns its field, resources are diminished, and
carrying capacity is altered. This is one way carrying capacity could be
increased for this population.
What is (e.g. high raingrasses flourish!)
Continue
100
This is the reason why shrubs and grasses are able to take root so quickly in
secondary succession.
What is there is soil already present
Continue
200
This type of succession occurs on a newly formed volcanic island (when no soil is
present)
What is primary succession
Continue
300
An example of a pioneer species.
What are lichen, mosses, etc.
Continue
400
What a pioneer species’ job is…
What is break down solid rock into soil
Continue
500
This is where succession is most likely to occur in an ocean.
What is a coral reef.
Continue
600
Fire is important for secondary succession. This is fire’s role.
What is fire helps return nutrients to the soil.
Continue
700
This is an example of the kind of tree that might first appear in primary
succession.
What is (LIST 1) cottonwoods, alders, or shrubs
Continue
800
These are two examples of types of events that might result in primary
succession.
What are glaciers, volcanoes, landslide, and strip mining.
Continue
900
This is the reason why primary succession will take much longer in
arctic areas than tropical areas.
What is soil takes longer to form (because rock is covered with snow, the growing season is shorter, and cold temperatures slow growth and
decomposition)
Continue
1000
A lichen is an example of a pioneer species. But “this” is what a lichen has
to do with “symbiosis”
What is a lichen is two different species (algae conducts photosynthesis and algae
collects water)
