A group of individuals of the same species in a particular area
community
population
ecosystem
biosphere
Community
all species in a particular area
all the species, biotic and abiotic factors in an area
one type of species
all life on Earth
Which of the following is an abiotic factor
sugar
rocks
plants
insects
Components of an environment that are living or from something living
abiotic
aquatic
acidic
biotic
The prey population distribution is limited by
too many prey
hours of sunlight
the type of food
predator removal
Which of the following is not abiotic
sunlight
wind
temperature
salinity
predators
The pattern of spacing among individuals within the geographic boundaries is called
boundaries
dispersion
pursuing
separation
(births + immigration) - (deaths + emigration) =
different trophic levels
population replacement
change in population size
evolution
What type of population growth model is this?
logistic
exponential
realistic
practical
When a population grows rapidly then reaches its carrying capacity, it is this type of growth model
bell curve
simplistic
logistic
hyperbole
Competition between different species
intraspecific
predator-prey
multi-attack
interspecific
The symbiotic relationship where both organisms benefit.
competition
mutualism
commensalism
predation
A symbiotic relationship where one organism benefits and the other is unaffected
mutualism
parasitism
competition
commensalism
The competitive exclusion principle states that two species with similar needs
cannot exist in the same place
need each other
benefit each other
always fight to the death
This figure shows that birds can coexist in the same area if they choose different niches.
location splitting
space sharing
predator-prey
resource partitioning
The role and location an organism has in an environment is its
niche
puprose
station
position
In this relationship, predators live on/in a host and depend on the host for nutrition
commensalism
parasitism
self defense
advantage relationship
Plants and animals can build up defense against predation through evolution
learning
species survival
adaptations
hibernation
Physical adaptations such as spines, horns, claws, larger eyes are
mechanical defenses
chemical defenses
odors
poison
When one species copies another species physical appearance for survival benefit
replication
surprise attacking
copying
mimicry
Food chains are hooked together into
food webs
complex chains
star patterns
food cycling
The links of a food chain represent energy steps called
power levels
trophic levels
food steps
prey levels
Detritivores do this
eat prey
create abiotic factors
transfer heat energy to plants
decompose dead organisms
In an energy pyramid, the bottom trophic level consists of
primary producers
animals
tertiary consumers
secondary consumers
What percentage of energy transfers up each level of the energy pyramid?
20
10
30
90
the build up of toxins form smaller to the larger organisms that eat them
poison building
bioaccumulation
toxin stock piling
environmental cleansing
These organisms that are introduced to an area they are not native to can hurt the native populations
invasive species
foreign creatures
exclusive species
plague
Succession that starts from rock
tertiary
seondary
primary
pioneering
Organisms that start the growth cycle in succession
beginners
pioneering organisms
climax community
establishers
It takes about 200 years with primary succession and about 50 years with primary succession to reach this conclusion
climax community
rich soil
land recycling
fire
In this cycle, CO2 is released by burning fossil fuels and by cellular respiration, only to consumed by plants
nitrogen cycle
carbon cycle
water cycle
energy cycle
when too much SO2 and NO2 are released into the atmosphere, this will result
nutrient rain
soil erosion
acid rain
fewer clouds
The ecological principles in developing ways to return degraded areas to natural conditions
turtle savin
building single family homes
archaeology
restoration ecology
