TYPES OF ORGANISMS
• AUTOTROPHIC:
-organisms that are able to make their own
food for energy.
EX: plants
• HETEROTROPHIC:
-organisms that consume food for energy.
EX: animals
ECOLOGY OF ORGANISMS
• BIOTIC FACTORS – LIVING components in the
environment.
EX: animals, plants, bacteria…
• ABIOTIC FACTORS- NON-LIVING components
in the environment – physical & chemical
characteristics.
EX: temperature, pH, humidity,
nitrogen..

Points
Population Demography
• The statistical study of populations
• Demos = people
• Graphy = measurement
POPULATION DYNAMICS
• BIRTH RATE= the # of births per yr.
• DEATH RATE=the # of deaths per yr.
• AGE STRUCTURE= distribution of species
ages within a population; this can lead to
life expectancy.
POPULATION GROWTH
• EMIGRATION= Movement of
individuals out of a population
• IMMIGRATION=Movement of
individuals into a population
EXPONENTIAL GROWTH
• If a population does not have any
restrictions, it can continually grow, BUT
in real life, there are limitations such as
food or predator relationships
that prevent a
THIS IS
population
from
KNOWN AS
THE J
growing
exponentially.
CURVE
What Can Limit Growth?
• Limiting factors are factors that limit the growth
of the population.
• Ex: Availability of food, Disease, Predators, Lack of
space, etc.
• These factors cause a S-Shaped growth curve.
