Chapter 1 Vocabulary Review
The behavioral and physical
characteristics of a species that
allow them to live successfully in
their environment.
 Adaptation
An interaction in which one
organism kills and eats another
organism
 Predation
A close relationship between two
species that benefits at least one of
the species.
 Symbiosis
The organism that benefits in
parasitism
 Parasite
Moving into a population
 Immigration
A relationship in which both species
benefit
 Mutualism
The process in which organism
make their own food using water,
sunlight, and carbon dioxide
 Photosynthesis
The organism that is harmed in
parasitism
 Host
An approximation of a number,
based on reasonable assumptions.
 Estimate
The organism that does the killing
 Predator
The series of changes that occur in
an area where the ecosystem has
been disturbed, but where soil and
organisms still exist.
 Secondary Succession
Living parts of an ecosystem
 Biotic factors
The series of predictable
changes that occur in a
community over time
 Succession
The number of births in a
population in a certain amount of
time.
 Birth rate
A group of organisms that are
physically similar and can mate
with each other and produce
offspring that can also mate and
reproduce.
 Species
The first species to populate the
area
 Pioneer species
Moving out of a population
 Emigration
A relationship in which one species
benefits and the other is
unaffected.
 Commensalism
The number of individuals in a
specific area
 Population density
Series of changes that occur in
an area where no soil or
organisms exist
 Primary Succession
The struggle between organisms to
survive as they attempt to use the
same limited resource.
 Competition
A relationship in which one
organism benefits and the other is
harmed.
 Parasitism
All the different populations living
together in an area
 Community
An organism’s particular role in its
habitat, or how it makes a living
 Niche
A method used to determine population size using the following
formula:
Total population =
(number of total individuals captured X number of originally marked )
Total number of individuals recaptured with mark
 Mark and Recapture
An environmental factor that
prevents a population from
increasing
 Limiting factor
The organism that is killed
 Prey
Counting every organism that you
see to determine population size
 Direct observation
The process by which
characteristics that make an
organism better suited for their
environment become more
common in that species.
 Natural Selection
The place where an organism lives
and that provides the things the
organism needs to survive.
 Habitat
Counting signs of an organism to
determine population size
 Indirect observation
Counting the number of individuals
in a small area and then
multiplying to find the number ina
larger area
 Sampling
All living things
 Organisms
The study of how living things
interact with each other and with
their environment.
 Ecology
The largest population that an
environment can support
 Carrying capacity
All the members of one species in a
particular area
 Population
Nonliving parts of an ecosystem
 Abiotic factors
The levels of ecological
organization from smallest to
largest.
 Organism, population, community,
ecosystem
The Great Oyster Sampling….
100 meters wide X
50 meters = ??
Pretend Oyster Bed……..
There are 20 oysters per
square meter, so how
many oysters would be in
an area this size?
•First find the area of the PRETEND
OYSTER bed….
•100 meters X 50 meters = 5,000
meters squared
•Then multiply your SAMPLE SIZE by
your AREA SIZE….
•5,000 meters squared X 20 oysters
per square meter = 100,000
oysters!!
