* 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 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
