Ecology is study of interactions between non-living components in the environment… light

Living organisms… Plants Animals microorganisms in soil, etc.

To study Ecology involves… For non-living (abiotic) Climatology Hydrology Oceanography Physics Chemistry Geology soil

Ecology… views each locale as an integrated whole of interdependent parts that function as

Nonliving dead organic matter nutrients in the soil and water. Producers green

Consumers herbivores and carnivores Decomposers fungi and bacteria Tundra Caribou

ECOLOGY: Levels of Organization - a hierarchy of organization in the

Levels of organization - Terms Biosphere Surface of the earth Composed of many

Levels of organization - Terms Population – one species live in one place at

Levels of organization - Terms Habitat – physical location of community Organism –

Very complex Can contain 100’s to 1000’s of interacting species.

THEN… Ecology is an integrated and dynamic study of the environment.
