ECOLOGY“ECO” “OIKOS” HOMES“OLOGY” The Study of
* Ecology = _______________
* Study of interactions or interrelationships between different living organisms and their environment
(3) Rules in ECOLOGY1.) EVERYTHING IS CONNECTED……..2.) SOMETHING THAT EFFECTS ONE
THING………3.) SYSTEM HANGS TOGETHER………
State of balance = __________*regulate body via this means
What is interdependence?All organisms interact with other organisms
in their surroundings and with the nonliving portion of their environment.
Each member is mutually dependent on the other
members Survival depends on these interactions
What is interdependence?ANY change in the environment can spread
through the network of interactionsCan affect organisms that appear far removed from
the change

Ecosystems: Biotic and Abiotic Factors
ECOSYSTEMAn area where different types of organisms
interact with each other and with the environment in a self perpetuating manner
Includes all the organisms and the nonliving environment found in a particular place.
What ecosystems do you see?
BIOTIC vs. ABIOTICLiving parts of an ecosystem
Kingdoms (5) - Protista- Monera- Fungi- Animalia- Plantae
List all the Biotic Factors you see:
List all the Biotic Factors you see:
BIOTIC vs. ABIOTICNon-living parts of an ecosystem
Deal with the physical environmentExample: water, climate, sunlight, air, soil
characteristics (pH level), altitude, topography (surface of land)
List all the Abiotic Factors you see:
Levels of OrganizationOrganism, Species, Population, CommunityEcosystemBiomeBiosphere
LEVELS OF ORGANIZATION (in an ecosystem)Organisms are organized into levels
Smallest most complexEach level:
has unique properties is influenced by processes at other levels
Levels organism, species, population, community , ecosystem
1.) ORGANISMAn individual
species in an ecosystem.
2.) SPECIESA group of similar
organisms that can mate with each other and produce fertile offspring.
3.) POPULATIONAll the
members of a particular number of species that live IN A CERTAIN PLACE AT A CERTAIN TIME.
4.) COMMUNITYAll the interacting
organisms (populations) that live in a certain area.
ONLY includes species of living organisms unlike ecosystems
5.) ECOSYSTEMAll living (biotic)
and nonliving (abiotic) things in the environment
