The place where an organism lives
out its life.
What is a habitat?
Column 1, #1
Biotic factors: living organisms
that inhabit an environment.
Ex: plants, animals
Abiotic factors: nonliving parts
of an organism’s environment.
ex: air currents,
Distinguish
betweentemperature,
biotic and
abiotic
factors
and soil
provide an
moisture,
light,
example of each.
Column 1, #2
1. Mutualism: both species benefit
2. Commensalism: one species benefits
and the other species is neither
harmed nor helped
3. Parasitism: harmful to one species
and beneficial to the other species.
Describe the three types of
symbiotic relationships: (1)
mutualism, (2) commensalism,
and (3) parasitism.
Column 1, #3
Niche.
What is the term used to
describe an organism’s
strategies and adaptations to
living in its environment?
Column 1, #4
1. Organism
2. Population
3. Community
4. Ecosystem
5. Biosphere
List the five levels of ecological
organization, from smallest to
greatest.
Column 1, #5
Producers: = autotrophs. uses light
energy or energy stored in chemical
compounds to make its own food.
Consumers: = heterotrophs. Cannot
make its own ood and feeds on other
organisms.
Distinguish between
producers and consumers.
Column 2, #1
(1)herbivores: obtain food from plants
(2)Carnivores: feed on other animals
(3)Omnivores: eat both plants and
animals
Distinguish between the following
types of consumers: (1)
herbivores, (2) carnivores, and (3)
omnivores.
Column 2, #2
adaptation
Which trophic level has the most
biomass, and why?
Column 2, #3
Matter recycles, but some energy is
transferred.
How does the movement of
energy and matter in
ecosystems differ?
Column 2, #4
Producers typically have the most
biomass because they have the
most amount of energy available to
them. 10 percent of the energy is
available for the next trophic level.
Which trophic level typically has
the most biomass, and why?
Column 2, #5
All the populations of different
species that live in the same place
at the same time.
What is a community?
Column 3, #1
Any biotic or abiotic factor that
restricts the growth of a population.
Ex: sunlight, climate, temperature,
water, nutrients, fire, soil chemistry,
space, other organisms.
What is a limiting factor?
Provide at least 2 examples of
limiting factors.
Column 3, #2
Tolerance is an organism’s ability to
withstand fluctuations in a limiting factor.
Populations become smaller as conditions
move toward either extreme.
What is tolerance? How does
a range of tolerance affect
the distribution of
organisms?
Column 3, #3
Primary succession takes place where there
are no living organisms and pioneer species
take hold. Secondary succession takes place
after an existing community is severely
disrupted.
Distinguish between primary
succession and secondary
succession.
Column 3, #4
Tundra- layer of permafrost, treeless, mostly
small mammals and insects
Taiga- trees, acidic soil, larger species of
animals
Distinguish between a tundra and a
taiga.
Column 3, #5
A group of the same species living in
the same place at the same time.
What is a population?
Column 4, #1
The number of organisms an environment
can support.
What is carrying capacity?
Column 4, #2
Exponential growth- J-shaped growth
curve. As a population gets larger, it
also grows at a faster rate.
S-Shaped growth curve- limiting
factors cause population growth to
slow.
Distinguish between
exponential growth and an Sshaped growth curve.
Column 4, #3
Density-dependent factors: have an increasing effect as the
population increases. Ex: disease, competition, predators,
predation, food
Density-independent factors: affect populations regardless
of their density. Ex: volcanic eruptions, temperature,
storms, floods, drought, chemical pesticides, forest fire,
human interference, animal behavior
Distinguish between densitydependent and densityindependent factors. Provide
an example of each.
Column 4, #4
Slow life-history pattern- large organisms, mature
and reproduce slowly, long life span. Ex:
whales, humans, plants.
Rapid life-history pattern- small organisms, mature
quickly, reproduce early, short life span. Ex:
mosquitoes, wild mustard plants
Distinguish between a rapid and slow lifehistory pattern.
Column 4, #5
The variety of species in a specific
area.
What is biodiversity?
Column 5, #1
Conservation biology- study and implementation of
methods to protect biodiversity. Ex: legal protection
of species, preserving habitats, habitat corridors,
sustainable use, captivity, reintroduction programs,
protecting plant species.
Describe some of the strategies
used in conservation biology.
Column 5,
#2
Endangered species- numbers are so
low that extinction is possible.
Extinction- disappearance of a
species. Last member dies.
Distinguish between and
endangered species and
extinct species.
Column 5, #3
Habitat fragmentation is the separation of
wilderness areas from other wilderness area.
Effects: increased extinction, disruption of
ecological processes, invasive species, increased
risk of fire, climate change
What is habitat
fragmentation and what
effect does it have on the
environment?
Column 5, #4
Exotic species- grow at an exponential rate because
they are not immediately vulnerable to local
competitors or predators as are native species. This
can lead to the disappearance of native species.
How can exotic species affect
populations of native species?
