Environmental resistance
The study of how organisms interact with
their environment
Living factors that influence an organism
The biotic and abiotic factors surrounding
an environment
A group of organisms of one species
living in an area at one particular time
Non-living (physical) factors that influence
an organism
All the communities and the physical
environment in an area
Populations of all the species in one area
An organism that obtains nutrients from
other organisms
An organism, such as plants, that make
their own food
The role or way of life of an organism in a
community
Inherited characteristics that allow
organisms to reproduce or survive more
effectively
Structures that help an organism to
survive
The place where an organism lives
Processes that organisms carry out to
survive
Ways in which members of a species act
individually or in a group, in order to
increase the chances of survival
Zone of conditions within which an
organism functions at its best
‘Ability to cope’ without compromising
health or breeding success
The limits, outside which, a factor can
cause physiological stress or death
The limits outside the optimum range, in
which an organism can survive but is
under stress
A change in an organism’s tolerance limits
Lianes
Exponential growth
Immigration
Organism
Biotic factor
Population
Ecosystem
Survivorship curve
Natality
Emigration
Equilibrium
Carrying capacity
Environmental constrain that limits the
growth of an organism or population
The numbers of individuals per unit area
of habitat at a specific time
The total number of organisms in a
population
Shows if a population is increasing, stable
or decreasing
Location of individuals in an area
Death rate
Graph showing the number of organisms
in a population that survive to a particular
age
Movement of organisms into a population
Birth rate
Extremely rapid growth (doubling every
time)
Movement of organisms out of a
population
The resistance experienced by a
population in exponential growth from the
environment as it fills it up
When the factors birth and death, and
immigration and emigration balance
Occurs independently on the size of the
population
Maximum size of population able to be
sustained in an environment
Vertical layers of plant species distribution
seen in forests
The effect depends on the size of the
population
Plants that grown up the trunk of trees
and are rooted into the ground
Bands or zones of species distribution
seen as a result of a gradient in some
environmental factor
Change in species distribution with time
Plants that are found growing from the
forks of trees and have no contact with
the soil
