Presentation transcript:

Components of an Ecosystem “parts of the environment”

Habitat  An environment that provides the things the organism needs to live, grow, and reproduce

Biotic  “Bio”=life  All the living and once living parts of a habitat  List 2 examples.

Abiotic  Prefix “A”=not, or opposite  All the non-living parts of a habitat  Water, sunlight, oxygen, temperature, soil

Population  All the members of one species in a particular area  All the pigeons in NYC  Prairie dog town

Communities  All the different populations in an area  Must be close enough to interact  Prairie dogs, ferrets, grass, hawks

Ecosystems  All the living organisms and non-living surroundings in an area  Prairie, forest, stream
