ECOLOGY “ECO”  “OIKOS”  HOMES “OLOGY”  The Study of * Ecology = _______________ * Study of interactions or interrelationships between different living organisms and their environment

(3) Rules in ECOLOGY 1.) 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 interactions Can affect organisms that appear far removed from the change Example: Bald Eagle – affected by DDT Example: Forests in the eastern United States  “When Nature Goes Nuts” Article

Biotic and Abiotic Factors

ECOSYSTEM An 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. Includes all the organisms and the nonliving environment found in a particular place.

What ecosystems do you see?

BIOTIC vs. ABIOTIC Living parts of an ecosystem Kingdoms (5) - Protista - Monera - Fungi - Animalia - Plantae

List all the Biotic Factors you see:

BIOTIC vs. ABIOTIC Non-living parts of an ecosystem Deal with the physical environment Example: water, climate, sunlight, air, soil characteristics (pH level), altitude, topography (surface of land)

List all the Abiotic Factors you see:

Organism, Species, Population, Community Ecosystem Biome Biosphere

LEVELS OF ORGANIZATION (in an ecosystem) Organisms are organized into levels Smallest  most complex Each level: has unique properties is influenced by processes at other levels Levels  organism, species, population, community, ecosystem

1.) ORGANISM An individual species in an ecosystem.

2.) SPECIES A group of similar organisms that can mate with each other and produce fertile offspring.

3.) POPULATION All the members of a particular number of species that live IN A CERTAIN PLACE AT A CERTAIN TIME.

4.) COMMUNITY All the interacting organisms (populations) that live in a certain area. ONLY includes species of living organisms unlike ecosystems

5.) ECOSYSTEM All living (biotic) and nonliving (abiotic) things in the environment

RECAP: (smallest to largest/most complex)

Levels of Organization Can you pick out the levels of organization in this ecosystem?. Name the examples of organism, species, population, community, and ecosystem.
