By Ms. Anderson

2. Ecosystem Organization
An ecosystem is made up of all the LIVING (Biotic) and NON-LIVING (abiotic) parts of an area.
As you revel each picture on this slide have students identify if it is a picture or living or non-living objects.

3. Ecosystem Organization
The living parts of an ecosystem are called BIOTIC FACTORS.
Biotic factors include any item that comes from a living organism, like eggs, fur, feces, feathers, snake skin, etc.

4. Ecosystem Organization
The non- living parts of an ecosystem are called ABIOTIC FACTORS.
Abiotic factors include temperature, wind, sunlight, fresh water, salt water, rainfall, etc. in an area

5. Ecosystem Organization
The organisms in an ecosystem can be organized into groups.
From simple to complex, the groups are:
Organism (Individual)
Population
Community
Ecosystem/Biome
Biosphere

6. Ecosystem Organization
Organism: an individual member of a species.
Example: An elk

7. Ecosystem Organization
Population: a group of individuals of the same species that live together.
Example: Herd of elk

8. Ecosystem Organization
Community: All of the populations of species that live and interact in an area.
Example: Mountain animals--eagles, elk and deer, wolves, bears, mountain lions

9. Ecosystem Organization
Ecosystem or Biome: Community of organisms plus the abiotic environment of the community.
Example: Mountain animals and forest climate

10. Ecosystem Organization
Biosphere: The part of Earth where life exists.
(From the deepest parts of the ocean to high in the air).
