Populations
Notes and Bell Quiz
NOTES - Carrying Capacity
The maximum number of individuals that
an environment can support.
Exponential Growth
Most populations of organisms grow this
way. Example: Humans and bacteria…..
Density –
Population
unit area
Species Diversity# of species in a
given area
Dispersion – Where individuals are found
in a habitat
Clumped
Random
Uniform
Density Dependent
Depends on the number
of individuals in a
population.
Examples: Disease,
Competition, Predation,
Crowding
Density Independent
Factors that affects a
population no matter
how many individuals.
Examples: Natural
Disasters,
Temperature,
Niche How a species
interacts with its
habitat or
environment.
Symbiosis  ecological relationship between two
different species
Competition Species A - / Species B Interaction where both species are harmed
Predation +/Interaction where one species is harmed
the other is benefited.
Parasitism +/Interaction where one species is harmed
and the other is benefited
Mutualism +/+
Interaction where both species are
benefited
Commensalism +/o
Interaction where one
species is benefited
and the other is
unaffected
Animals Adaptations
1. Camouflage
2 Mimicry
 3 Chemical properties
4 Self defense mechanisms
Others
Distraction displays – bird saving it’s nest
Autonomy – sacrifice limbs
Markings
Armor
